Appointment Elizabeth II, following Gordon Brown's resignation as prime minister on 11 May 2010, extended an invitation to Cameron to establish a new administration based on Brown's recommendation. At age 43, Cameron became the youngest prime minister since
Lord Liverpool in 1812, beating the record previously set by Tony Blair in May 1997. In his first address outside
10 Downing Street, he announced his intention to form a
coalition government, the first since the
Second World War, with the Liberal Democrats. Cameron outlined how he intended to "put aside party differences and work hard for the common good and for the national interest".In June 2010, Cameron described the economic situation as he came to power as "even worse than we thought" and warned of "difficult decisions" to be made over spending cuts. By the beginning of 2015, he was able to claim that
his government's austerity programme had succeeded in halving the
budget deficit, although as a percentage of
GDP rather than in cash terms. In December 2010, Cameron attended a meeting with
FIFA vice-president
Chung Mong-joon, in which a vote-trading deal for the right to host the 2018 World Cup in England was discussed.
Domestic affairs Welfare and benefits Upon entering office in May 2010, Cameron positioned social reform as integral to his government's broader ambition to tackle poverty and restore social responsibility. He promoted a "life chances" agenda that framed poverty not only in material terms, but in terms of a lack of opportunity and generational disadvantage. The government announced its intention to adopt a "lifecycle approach" targeting family life, education, mental health and addiction through coordinated interventions across those domains. Cameron extended reforms into broader public services through the "
Big Society" agenda. A 2011 white paper proposed opening schools, hospitals, and council-run services to non‑public providers under "payment‑by‑results" contracts, with aims of improving efficiency and innovation through increased choice and competition. In December 2015, due to sustained concern over failing children's services, Cameron announced that persistently underperforming local authorities would be required to transfer services to high‑performing councils, independent charities, or spin‑out organisations—a structural reform intended to improve outcomes and accountability. Cameron's also government enacted welfare reforms, including the introduction of
Universal Credit and the so‐called "
bedroom tax", aimed at reducing welfare spending and encouraging labour market participation. These reforms were linked in academic studies to negative social outcomes—such as increased crime and welfare losses in deprived areas—even beyond fiscal savings. Cameron's government in May 2016 directed reforms specifically for social workers and those leaving care. Legislation envisaged a statutory care‑leaver covenant obliging local authorities to provide detailed entitlements up to age 25 in areas such as housing, employment, and health support. Additionally, mandatory mentoring for care‑leavers and a shift in the balance of decision‑making to favor adoption over temporary foster placements were introduced to promote stability for vulnerable children.
Constitutional referendums As a part of the deal to enter into coalition with the
Liberal Democrats, the Conservatives pledged to hold a
referendum on a
2011 alternative voting system. The referendum was held in May 2011 and proposed replacing the current
first-past-the-post voting system with an
alternative voting system, it was defeated at the polls and later go on to be a catalyst for the fall of the Liberal Democrats. Cameron agreed to holding the
2014 Scottish independence referendum and eliminated the "
devomax" option from the ballot for a straight out yes or no vote. His support for the successful
Better Together campaign extended to making a successful request to the Queen to intervene. He had also backed a successful campaign to retain the status quo in a
referendum on changing the voting system, held at the request of his coalition partners. The 2016 referendum on the UK's membership of the European Union meant that his tenure as British prime minister saw an unprecedented three referendums on the UK's constitutional future.
Social reforms in 2012|alt=Cameron at Prime Minister's Questions in 2012Cameron supported the introduction of
gay marriage, despite more of his own Conservative MPs voting against the move than for it, meaning the support of Lib Dem MPs in government and Labour MPs in opposition was required to allow it to pass. Earlier in his term, he had managed to secure a huge majority for UK participation in UN-backed military action in Libya, but Cameron became the first prime minister
since 1782 to lose a foreign policy vote in the House of Commons over proposed military action against
Bashar al-Assad's regime in Syria. Subsequently, Barack Obama asked
congressional approval, which was not ultimately granted.
Education Cameron advocated a substantial expansion of
academy and
free school provision in England, positioning them as central to improving standards. From May 2010 to mid‑2014, the number of academies soared from 203 to over 4,600, with more than half of secondary schools operating under academy status by mid‑2013. He pledged to open at least 500 additional free schools by 2020, aiming to create around 270,000 new places, and announced the launch of 31 free schools in mid‑2016 alone, offering approximately 20,000 extra places. Under Cameron's government, the national curriculum underwent revision to make it more challenging for
state schools embedding early exposure to subjects such as
computing, advanced
mathematics,
geography and
history thinking from age five onwards. In December 2014, his government launched a £67 million initiative to retrain approximately 15,000 teachers in
STEM subjects, and offered bursaries to attract top university graduates in maths and physics into teaching roles. Parallel to this were proposals for a
National Teaching Service designed to deploy high‑quality educators to poorly performing schools, and expanded powers for regional school commissioners to intervene swiftly in inadequately rated schools. Cameron introduced the
pupil premium in 2011, allocating additional per-pupil funding to schools serving students eligible for free school meals. The aim was to mitigate socioeconomic disparities by directing more resources to disadvantaged pupils, supporting social mobility through enhanced educational opportunity.
Economy In response to the
Great Recession, Cameron undertook the austerity programme. This was presented by the Cameron administration as deficit reduction programme consisting of sustained reductions in public spending, which the government argued would reduce the
government budget deficit and the
welfare state in the United Kingdom. The
National Health Service and education were "
ringfenced" and protected from direct spending cuts. Cameron and Chancellor George Osborne claimed they aimed to eliminate the structural deficit (i.e. deficit on current spending as opposed to investment), and to have government debt falling as a percentage of GDP. By 2015 the deficit as a percentage of GDP had reduced to half what it was in 2010. Between 2010 and mid-2015, unemployment fell from around 7.9% to about 5.5% as employment expanded by roughly 2.45 million jobs. Economic growth remained modest, often described as sluggish, with GDP growth rates of around 0.4–0.8 % in the later years of the coalition. While the deficit declined, national debt rose from circa 71% of GDP in 2010 to approximately 84% by 2016. Critics and some economic commentators have argued that austerity slowed recovery and constrained growth — illustrating the risk of premature fiscal tightening in a weak economy.
Immigration Cameron said immigration from outside the EU should be subject to annual limits. He said in July 2013 that "in the last decade we have had an immigration policy that's completely lax. The pressure it puts on our public services and communities is too great." In 2015
The Independent reported: "The Conservatives have failed spectacularly to deliver their pledge to reduce net migration to less than 100,000 a year. The
Office for National Statistics (ONS) announced a net flow of 298,000 migrants to the UK in the 12 months to September 2014—up from 210,000 in the previous year."
Defence and foreign affairs Defence cuts , October 2014|alt=Cameron visiting British troops in Afghanistan in October 2014 In 2014 Cameron dismissed warnings that his cuts to the UK defence budget had left it less than a "first class-player in terms of defence" and no longer a "full partner" to the United States. In the
July 2015 budget, Chancellor George Osborne announced that the UK defence spending would meet the NATO target of 2% of GDP.

London Conference on Libya, March 2011|alt=Cameron with William Hague speaking to Anders Fogh Rasmussen at the London Conference on Libya in March 2011 Cameron condemned the violence used against anti-Gaddafi protesters at the beginning of the
Libyan Civil War After weeks of lobbying by the UK and its allies, on 17 March 2011, the
United Nations Security Council approved a
no-fly zone to prevent government forces loyal to
Muammar Gaddafi from carrying out air attacks on
anti-Gaddafi rebels. Two days later, the UK and the United States fired more than 110
Tomahawk missiles at targets in Libya. Cameron said he was "proud" of the role United Kingdom played in the overthrow of Gaddafi's government. Cameron also stated that UK had played a "very important role", adding that "a lot of people said that Tripoli was completely different to Benghazi and that the two don't get on—they were wrong. ... People who said 'this is all going to be an enormous swamp of Islamists and extremists'—they were wrong". In 2015 through 2016 the
Foreign Affairs Select Committee conducted an extensive and highly critical inquiry into the British involvement in the civil war. It concluded that the early threat to civilians had been overstated, and that the significant Islamist element in the rebel forces had not been recognised, due to an intelligence failure. By mid-2011, the initial limited intervention to protect Libyan civilians had become a policy of
regime change. However, that new policy did not include proper support for a new government, leading to a political and economic collapse in Libya, and the growth of
ISIL in North Africa. It concluded that Cameron was ultimately responsible for this British policy failure. US president Barack Obama also acknowledged there had been issues with following up the conflict planning, commenting in an interview with
The Atlantic that Cameron had allowed himself to be "distracted by a range of other things".
Falklands In 2013 in response to Argentina's calls for negotiations over the
Falkland Islands' sovereignty,
a referendum was called, asking
Falkland Islanders whether they supported the continuation of their status as an
Overseas Territory of the United Kingdom. With a turnout of 91.94%, an overwhelming 99.8% voted to remain a British territory, with only three votes against. In light of this, Cameron said: "We believe in the Falkland islanders' right to self-determination. They had a referendum. They couldn't have been more clear about wanting to remain with our country and we should protect and defend them".
Saudi Arabia (second left) and
Mo Farah (right) outside 10 Downing Street|alt=Cameron hosting a hunger summit with Pelé and Mo Farah outside 10 Downing Street Cameron supported
Britain's close relationship with Saudi Arabia. In January 2015 he travelled to the Saudi capital
Riyadh to pay his respects, following the death of the nation's
King Abdullah. According to
WikiLeaks, Cameron initiated a secret deal with Saudi Arabia, ensuring both countries were elected onto the
UN Human Rights Council. The same year his government announced "firm political support" for the
Saudi Arabian-led intervention in Yemen against the
Shi'a Houthis, re-supplying the Saudi military with weapons and providing them with training.
Sri Lanka Cameron reiterated calls for an independent investigation into the
alleged war crimes during the final stages of the Sri Lankan Civil War. "There needs to be proper inquiries into what happened at the end of the war, there needs to be proper human rights, democracy for the
Tamil minority in that country" Cameron stated. He stated that, if this investigation was not completed by March 2014, he would press for an independent international inquiry. This followed a visit to
Jaffna, a war-ravaged town in the northern part of Sri Lanka; Cameron was the first foreign leader to visit Jaffna since the island once colonised by Britain became independent in 1948. Cameron was mobbed by demonstrators, mostly women, seeking his assistance in tracing
missing relatives.
Turkey In a speech in
Ankara in July 2010, Cameron stated unequivocally his support for
Turkey's accession to the EU, citing economic, security and political considerations, and claimed that those who opposed Turkish membership were driven by "protectionism, narrow nationalism or prejudice". In that speech, he was also critical of Israeli action during the
Gaza flotilla raidwhich had killed nine Turkish activistsand
its Gaza policy, and repeated his opinion that Israel had turned Gaza into a "prison camp", These views were met with mixed reactions. The Cameron government declined to formally recognise
the Ottoman Empire's massacres of Armenians as a "genocide". During the EU referendum campaign, Cameron stated that Turkey was unlikely to be ready to join the EU "until the year 3000", at its current rate of progress.
Israel At the end of May 2011 Cameron stepped down as patron of the
Jewish National Fund, becoming the first British prime minister not to be patron of the charity in the 110 years of its existence. In a speech in 2011, Cameron said: "You have a prime minister whose commitment and determination to work for peace in Israel is deep and strong. Britain will continue to push for peace, but will always stand up for Israel against those who wish her harm". He said he wanted to reaffirm his "unshakable" belief in Israel within the same message. He also voiced his opposition to the
Goldstone Report, claiming it had been biased against Israel and not enough blame had been placed on Hamas. In March 2014, during his first visit to Israel as prime minister, Cameron addressed Israel's
Knesset in
Jerusalem, where he offered his full support for peace efforts between Israelis and Palestinians, hoping a two-state solution might be achieved. He also made clear his rejection of trade or academic boycotts against Israel, acknowledged Israel's right to defend its citizens as "a right enshrined in international law", and made note of the
Balfour Declaration of 1917, as "the moment when the State of Israel went from a dream to a plan, Britain has played a proud and vital role in helping to secure Israel as a homeland for the Jewish people." Senior Foreign Office minister
Baroness Warsi resigned over the Cameron government's decision not to condemn Israel for the
2014 Israel–Gaza conflict, saying that the government's "approach and language during the current crisis in Gaza is morally indefensible".
Military intervention in Iraq and Syria during the
2010 G20 Toronto summit|alt=Cameron meeting Barack Obama during the 2010 G20 Toronto summit In August 2013 Cameron lost a motion in favour of bombing Syrian armed forces in response to the
Ghouta chemical attack, becoming the first prime minister to suffer such a foreign-policy defeat since 1782. In September 2014, MPs passed a motion in favour of British planes joining, at the request of the Iraqi government, a bombing campaign against
Islamic State (IS) targets in Iraq; the motion explicitly expressed parliament's disapproval of UK military action in Syria. Cameron promised that, before expanding
UK air strikes and ground support to include IS units in Syria, he would seek parliamentary approval. In July 2015 a
Freedom of Information (FOI) request by
Reprieve revealed that, without the knowledge of UK parliamentarians, RAF pilots had, in fact, been bombing targets in Syria, and that Cameron knew of this. The prime minister, along with Defence Secretary
Michael Fallon, faced strong criticism, including from Conservative MPs, for not informing the Commons about this deployment; the Ministry of Defence said that the pilots concerned were "embedded" with foreign military forces, and so were "effectively" operating as such, while Fallon denied that MPs had been, as he put it, "kept in the dark". The Reprieve FoI request also revealed that British drone pilots had been embedded, almost continuously, with American forces at
Creech Air Force Base since 2008. These drone operators, who were "a gift of services", meaning the UK still paid their salaries and covered their expenses, had been carrying out operations that included reconnaissance in Syria to assist American strikes against IS. Fallon said that it was "illogical" for the UK not to bomb ISIL in Syria, for the organisation does not "differentiate between Syria and Iraq" and is "organised and directed and administered from Syria". Following the
terrorist attacks on Paris in November 2015, for which Islamic State claimed responsibility, Cameron began pushing for a strategy for the
Royal Air Force to bomb Syria in retaliation. Cameron set out his case for military intervention to Parliament on 26 November, telling MPs that it was the only way to guarantee Britain's safety, and would be part of a "comprehensive" strategy to defeat IS. On 3 December 2015, MPs voted 397–223 in favour of launching air strikes against ISIL targets in Syria. The vote for military action was supported by all but seven members of the Parliamentary Conservative Party, as well as 66 Labour MPs who backed the government in defiance of their leader,
Jeremy Corbyn, who had expressed his opposition to air strikes.
2015 general election Cameron was re-elected UK prime minister on 7 May 2015 with a majority in the Commons. The Conservative Party's decisive victory in the general election was a surprise, as most polls and commentators had suggested the outcome was too close to call and that the result would be a second hung parliament. Cameron said of his first term when returned as prime minister for a second term that he was "proud to lead the first coalition government in 70 years" and offered particular thanks to Clegg for his role in it. Forming the first
Conservative majority government elected since
1992, David Cameron became the first prime minister to be re-elected immediately after a full term with a larger popular vote share since
Lord Salisbury at the
1900 general election. In response to the November 2015 Paris attacks, Cameron secured the support of the House of Commons to extend air strikes against
ISIS into Syria. Earlier that year, Cameron had outlined a five-year strategy to counter Islamist extremism and subversive teachings.
2016 referendum and resignation As promised in the election manifesto, Cameron set a date for a
referendum on whether the UK should remain a member of the European Union, and announced that he would be campaigning for Britain to remain within a "reformed EU". The terms of the UK's membership of the EU were
re-negotiated, with agreement reached in February 2016. The option to leave came to be known as
Brexit (a
portmanteau of "British" and "exit"). The referendum was held on 23 June 2016. The result was approximately 52% in favour of leaving the European Union and 48% against, with a turnout of 72%. On 24 June, a few hours after the results became known, Cameron announced that he would resign the office of prime minister by the start of the Conservative Party Conference in October 2016. In a speech the next day outside 10 Downing Street, he stated that, on account of his own advocacy on behalf of remaining in the EU: "I do not think it would be right for me to try to be the captain that steers our country to its next destination." There was some strong criticism made of Cameron and his government following the referendum. Matthew Norman, in an opinion piece in
The Independent, called the referendum an act of "indescribably selfish recklessness". In late July, Parliament's Foreign Affairs Select Committee was told that Cameron had refused to allow the Civil Service to make plans for Brexit, a decision the committee described as "an act of gross negligence". His farewell speech as he left No. 10 accompanied by his family stressed the value of selfless public service. The
Conservative Party leadership election was scheduled for 9 September and the new leader was expected to be in place by the autumn conference, set to begin on 2 October. On 11 July, following the withdrawal of
Andrea Leadsom from the Conservative Party leadership election and the confirmation of
Theresa May as the new
leader of the Conservative Party, Cameron announced he would hold a final cabinet meeting on 12 July and then, following a final Prime Minister's Questions, submit his resignation to the Queen on the afternoon of 13 July. Cameron delivered his resignation speech in front of 10 Downing Street on 11 July. Cameron's resignation speech attracted further attention when he walked away humming a tune, picked up by microphone, after he had finished his speech. After his final Prime Minister's Questions, Cameron received a standing ovation from MPs; his final comment was, "I was the future once"—a reference to his 2005 quip to Tony Blair, "he was the future once". Cameron then submitted his resignation to the Queen later that day. Although no longer serving as prime minister, Cameron originally stated that he would continue inside Parliament, on the Conservative
backbenches. On 12 September, however, he announced that he was resigning his seat with immediate effect, and was appointed to the
Manor of Northstead. He was succeeded as MP for Witney by fellow Conservative
Robert Courts.
The Washington Post described him as having "sped away without glancing back" once
Theresa May had "vaulted herself out of the hurricane-strength political wreckage of Britain's vote to leave the European Union." ==Post-premiership (2016–present)==
