Kerr topped the Scottish Conservative list for
Central Scotland in the
2021 Scottish Parliament election, and also sought election in the
Falkirk West constituency. He took 18.5% of the vote in Falkirk West, placing him a distant third. Having been unsuccessful on the constituency vote, the Conservatives were entitled to three seats on the Central Scotland list, with Kerr being elected, alongside
Graham Simpson and
Meghan Gallacher. He took his seat on 10 May 2021. Upon his election, Kerr was given the role of Chief Whip for the Scottish Conservatives in Holyrood, replacing
Miles Briggs. On the 28 May, Kerr used his
maiden speech to urge the Cabinet Secretary for Health,
Humza Yousaf, to speed up rollout of the
COVID-19 vaccine. He was later elected as convenor of the Education, Skills and Young People committee on 23 June. On 12 January 2022, Kerr called for
Boris Johnson to resign as Conservative party leader and Prime Minister over the
Westminster lockdown parties controversy along with a majority of Scottish Conservative MSPs. In a mini-reshuffle in September 2022, Kerr was moved to be the Shadow Secretary for Education and Skills, shadowing
Shirley-Anne Somerville. He was replaced as Scottish Conservative Chief Whip by
Alexander Burnett. In January 2023, Kerr wrote an article for the Daily Telegraph calling on reforms of the Scottish Parliament to offer greater scrutiny of the Scottish Government, arguing that Holyrood proceedings were "rigorously controlled" by Scottish Ministers and accused SNP backbenchers of "scripted questions". Kerr's article sparked debate across Scotland, with Kerr's arguments being supported by former SNP Government ministers. Kerr caused controversy on 14 April 2023 in a now deleted tweet when he suggested transgender people have learning disabilities and has since apologised. As Shadow Secretary for Education and Skills, Kerr called for many reforms within Scottish Education, including a new deal for teachers. Kerr highlighted the rise in violent attacks in the classroom, successfully persuading the Government to hold a national discussion to address this problem. Kerr gained internet fame as "A Potato With More Vitamin C Than a Lemon" after debating motion S6M-05292 at the Scottish Parliament entitled "Stephen Kerr: A Potato With More Vitamin C Than a Lemon". In June 2023, Kerr was announced as the Conservative candidate for the new
Angus and Perthshire Glens seat ahead of the
2024 general election. In the election, he finished second to
Dave Doogan of the SNP, taking 14,272 votes (30.1%). On 14 August 2024, Kerr accidentally published doubts about his endorsed candidate
Murdo Fraser in the
leadership election as a status update on
WhatsApp. As of October 2024, Kerr is a member of the Constitution, Europe, External Affairs, and Culture Committee at Holyrood. Kerr is standing in
Stirling at the
2026 Scottish Parliament election. == Personal life ==
