Early backbench career Baker was selected as the Conservative candidate for Wycombe on 31 October 2009, after former Conservative MP
Paul Goodman stood down. winning 48.6% of the vote and a majority of 9,560. Baker was rated as one of the Conservatives' top 10 most rebellious MPs of the 2010 intake. He was nominated as a 'Newcomer of the Year' on
ConservativeHome. He was named as the most authoritative Member of Parliament on Twitter in January 2011. In March 2011, Baker initiated an
adjournment debate alleging a malicious prosecution of an operator of an independent mental health unit. The
Solicitor General Edward Garnier issued an apology. That year, Baker attracted controversy after he was one of three Conservative MPs who went on a luxury trip to Equatorial Guinea, funded by the Government of the state, via a trust based in Malta. They reported at the end of the trip that human rights violations in the country were "trivial", in contrast to
Amnesty International, which had reported repeated incidents of torture in the country. Baker campaigned for banking reform, calling for banks to re-adopt
Generally Accepted Accounting Practice to account for devalued loans, as well as failed ones; in May 2011, he calculated that the use of IFRS instead of GAAP over-stated the strength of
Royal Bank of Scotland's balance sheet by £25bn. He introduced a
Ten Minute Rule bill to 'bring casino banking into the light', by changing rules by which banks account for derivatives. He was elected to the executive of the
1922 Committee on 16 May 2012, saying he was 'fed up with factionalism' and wanted 'to stand as neither a modernising 301 candidate or a traditionalist'. At the
2015 general election, Baker was re-elected, increasing his share of the vote to 51.4% and increasing his majority to 14,856. In June 2015 he became co-chair of
Conservatives for Britain, a campaigning organisation formed of
Eurosceptic MPs. Baker was shortlisted for the
Grassroot Diplomat Initiative Award in 2015 for the founding of the Cobden Centre, and remains in the directory of the Grassroot Diplomat Who's Who publication. In 2017, the
Unite Union raised concerns that Baker had lobbied for the deregulation of white asbestos. In 2010, in a series of parliamentary questions, Baker asked the Work and Pensions Secretary: "If he will bring forward proposals to distinguish the white form of asbestos and the blue and brown forms of that substance", also questioning: "If he will commission an inquiry into the appropriateness of the health and safety precautions in force in respect of asbestos cement." Baker became chair of the ERG, a pro-
Brexit group of Conservative MPs, on 20 November 2016. At the snap
2017 general election, Baker was again re-elected, seeing his share of the vote decrease to 50% and his majority decrease to 6,578.
Ministerial career (2017–2018) In February 2018, as a minister in the
Department for Exiting the European Union, Baker was forced to apologise after inaccurately claiming that civil servants had deliberately produced negative economic models to influence policy. Answering questions in the House of Commons, Baker confirmed a claim by the Eurosceptic backbencher
Jacob Rees-Mogg that Charles Grant, the Director of the
Centre for European Reform, had reported that Treasury officials "had deliberately developed a model to show that all options other than staying in the customs union were bad, and that officials intended to use this to influence policy". Audio then emerged of the event in question, which showed that Grant had not made the comments attributed to him. By the time the audio was released by
Prospect magazine, the Prime Minister's spokesman had already backed Baker's claims. The spokesman later said that Baker had made a "genuine mistake". On 8 July 2018, Baker resigned following the resignation of the
Brexit Secretary,
David Davis after working on a
Brexit white paper which Baker said "did not accord with what was put to the cabinet" a few days earlier. He was appointed Deputy Chair of the ERG shortly after and
de facto chief whip.
Return to the backbenches (2018–2022) On 22 October 2018, Baker submitted a letter of no confidence in Theresa May's leadership over her Brexit Withdrawal Agreement proposals, stating that he had become convinced it was not possible to "separate the person from the policy." A few days earlier, Baker had told fellow members of the European Research Group that by his count they likely already had the 48 letters necessary to trigger a motion of no confidence in Theresa May's leadership, and told
BBC Politics they were "pretty close" to getting them "with a dozen more probables on top". At the
2019 general election Baker was again re-elected with a decreased vote share of 45.2% and a decreased majority of 4,214. He again became Chair of the ERG before resigning in 2020. In May 2020 he called for
Dominic Cummings's resignation. He is a steering committee member of the
COVID Recovery Group, a group of Conservative MPs who opposed the UK government's
December 2020 lockdown.
The Telegraph described them as being seen by Westminster as an "echo" of the Brexiteer ERG, and a response by backbench Conservatives to
Nigel Farage's anti-lockdown
Reform UK party. with him as its new chairman. In April 2022, in the wake of the
Partygate scandal surrounding British Prime Minister
Boris Johnson, Baker stated in the House of Commons that "the gig is up" and that Johnson should be "long gone by now". He said this two days after he had praised the prime minister's new apology given that week for his actions during the period of behaviour restrictions imposed over the COVID pandemic. Following the resignation of Johnson in July, Baker considered a possible candidacy to succeed him, but ultimately chose not to stand and endorsed
Suella Braverman. He later endorsed
Liz Truss's successful bid for the leadership.
Return to government (2022–2024) On 7 September 2022, he was appointed
Minister of State in the
Northern Ireland Office under Prime Minister Liz Truss in
her ministry. The appointment came at a sensitive time with the government facing challenges over the
Northern Ireland Protocol. Baker endorsed Rishi Sunak in the October 2022 Conservative Party leadership election and was subsequently reappointed as
Minister of State for Northern Ireland. He was appointed Minister of State for the Cabinet Office in February 2024, with the responsibility for carrying through the implementation of the
Windsor Framework. After serving as an MP for 14 years, Baker was defeated in the
2024 general election for Wycombe, losing to Labour candidate
Emma Reynolds, who beat Baker with a majority of 4,591. == Post-parliamentary career ==
