Early career and Scottish Parliament Cole-Hamilton stood in several constituencies unsuccessfully as a Lib Dem candidate: at the 2003 Scottish Parliament election for the Kirkcaldy constituency; at the 2005 general election for Kirkcaldy and Cowdenbeath; in 2007 for Stirling and in 2011 for Edinburgh Central. conference in the
Bournemouth International Centre in 2017. Following the
2015 general election, Deputy Prime Minister and Liberal Democrat Leader
Nick Clegg quoted Cole-Hamilton when delivering his resignation speech. He referred to the 2011 Scottish Parliament election, saying "In 2011 after a night of disappointing election results for our party in Edinburgh, Alex Cole-Hamilton said this: if his defeat was part-payment for the ending of child detention, then he accepted it with all his heart. Those words revealed a selfless dignity which is very rare in politics, but common amongst Liberal Democrats." In May 2016, Cole-Hamilton was elected to the Scottish Parliament for the Edinburgh Western constituency. After the election, he was made Liberal Democrat in Scotland spokesperson for Health. Cole-Hamilton's 2016 electoral expenses were investigated in June of the following year, according to the
Edinburgh Evening News: "Mr Cole-Hamilton recorded the highest election costs of any Edinburgh candidate, spending £32,549 on his campaign while his rival for the Edinburgh Western seat, SNP candidate Tony Giugliano, spent £18,593." While Cole-Hamilton was cleared of any wrongdoing, the party was fined for failing to file an accurate spending return on its national spending return. He received the 'one to watch' award at the Herald – Scottish Politician of the Year Awards in August 2016. In 2018, Cole-Hamilton successfully persuaded the Scottish Government to reverse a planned funding cut to
HIV Scotland that would have sunk that organisation. In 2020, during parliamentary deliberation of the first Coronavirus Act, Cole-Hamilton introduced amendments which forced a government U-turn on their proposals to abolish jury trials in Scotland for the duration of the emergency. From 2019 until March 2021, he was a member of the
Committee on the Scottish Government Handling of Harassment Complaints against the former First Minister,
Alex Salmond. In February 2021, Cole-Hamilton was forced to apologise after having been seen swearing at
Minister for Children and Young People Maree Todd during an online committee hearing. He wrote Todd a letter of apology, as well as publicly apologising in the Holyrood Chamber the week after, saying his language was “neither parliamentary nor respectful.”
The National reported in February 2024 that revisions to Cole-Hamilton’s
Wikipedia article relating to the incident were ‘removed’ via a computer in the Scottish Parliament. At the
2021 Scottish Parliament election, Cole-Hamilton received 25,578 votes, the highest number of votes ever cast for a single candidate in the Scottish Parliament election. He beat the runner-up, SNP candidate Sarah Masson, by 9,885 votes.
Leader of the Scottish Liberal Democrats On 27 July 2021, Cole-Hamilton announced his intention to stand in the upcoming
Scottish Liberal Democrats leadership election to replace
Willie Rennie. He won the election unopposed on 20 August 2021 and took office the same day. He led the party into the 2022 local elections, which saw an increase of 20 councillors to 87, and increased vote share to 8.7%. He has prioritised campaigning on children's mental health, long covid, tackling the climate crisis and supporting Ukrainian refugees. He was sanctioned by the
Kremlin in August 2022 following his public criticism of the
Russian invasion of Ukraine, and his efforts to highlight Russian influence in Scotland. Cole-Hamilton spoke at an
Oxford Union debate on
Scottish independence on 24 February 2023, during which he compared the Yes movement with the push for
Brexit. This was criticised by
Corri Wilson, deputy general secretary of the independence-supporting
Alba Party. In December 2023, Cole-Hamilton was criticised after he attempted to take part in a parliamentary debate through video link from outside the parliamentary bar. He disagreed with
First Minister John Swinney's attempts to exclude
Reform UK from a across-party summit to counter the far-right, telling
BBC Scotland that he had “deep concerns about anything which aims to stifle a democratically elected voice" preferring instead to defeat arguments he disagrees with in "open ground".
2024 general election Upon
Humza Yousaf’s resignation as
First Minister in May 2024, Cole-Hamilton submitted his name for nomination as Scotland's next FM. He received four votes at the First Minister selection, losing to
John Swinney who succeeded Yousaf as the leader of the
SNP. After
Rishi Sunak called a
general election on 22 May, Cole-Hamilton began campaigning for the Lib Dems, looking to “tear down the acid yellow wall of the SNP”. Cole-Hamilton said the campaign would purposely avoid mentioning Scottish independence as an issue. He instead prioritized housing, education, and NHS dental care among other issues. Cole-Hamilton represented the Lib Dems in a
STV debate on 3 June, the first debate of the general election. He participated in another debate on 11 June hosted by
BBC Scotland. On 17 June, Cole-Hamilton unveiled the Scottish Lib Dems manifesto, which called for more funding for local agriculture, a new minimum wage for care workers, and more support to mental health services, among other issues. He also promised to cut energy bills and fix Scotland's "broken" relationship with Europe. On 26 June, he said he had placed bets on elections in Scottish constituencies, describing them as "low-level bets" to "show confidence in my friends". In the 2024 election the Lib Dems won 72 seats, the most ever in its history. The party won 6 seats in Scotland, gaining two in
Inverness, Skye and West Ross-shire and
Mid Dunbartonshire from the SNP. The former (previously known as
Ross, Skye and Lochaber) was held by former Lib Dem leader
Charles Kennedy from 2005 to 2015. Cole-Hamilton celebrated the results, declaring “There are far more
liberals than
nationalists on the benches of the
House Commons today.”
Foreign politics In October 2024, Cole-Hamilton announced he would be campaigning in the American
swing state of
Pennsylvania to knock on doors for the
presidential campaign of
Vice President Kamala Harris, the
Democratic Party nominee in the
2024 election. He said he and three other Liberal Democrats booked flights as soon as
Joe Biden suspended his
campaign in July, and described the election as “one of the most important elections in global history.” Cole-Hamilton also campaigned for
Barack Obama during his
2008 presidential campaign.
2026 Scottish Parliament election In April 2025, he welcomed former Conservative MSP
Jamie Greene into the Scottish Liberal Democrats, who cited the rise of “
right-wing populism” in his former party as the reason for his defection. Cole-Hamilton described Greene an "effective communicator" who possessed "symmetry with our outlook and our values as a party". Cole-Hamilton would later write that Greene's defection to the Lib Dems "felt like a scene from a
John le Carré spy novel." Speaking on the BBC’s
The Sunday Show, Cole-Hamilton asserted he was comfortable with centre-right MSPs being a part of the Liberal Democrats. He also predicted that more defections would follow, believing Greene's actions spoke to a greater 'realignment' in
Scottish politics. At the party's spring conference held in April 2025, Cole-Hamilton announced that they would prioritize
The Highlands at the
next Holyrood election, specifically targeting the seats of
Kate Forbes and
Maree Todd of the SNP. At the Liberal Democrats national autumn party conference held in
Bournemouth on 21 September 2025, Cole-Hamilton pledged that the party would overtake the
Scottish Tories in
Holyrood, and urged disaffected moderate conservatives to support the Scottish LibDems. He also committed to not forming a coalition with the
SNP after the election. == Personal life ==
