Sir David Roy Lidington KCB CBE (born 30 June 1956) is a former British politician who was the Member of Parliament (MP) for Aylesbury from 1992 until 2019.

[2][3] Between 2010 and 2016, he served as Minister of State for Europe holding the position for the entirety of David Cameron's premiership, a longer period than any of his predecessors.

Theresa May appointed him to the cabinet for the first time in June 2016, where he held a number of roles including Leader of the House of Commons, and the joint title of Lord Chancellor and Secretary of State for Justice.

[10] Lidington's early employment included posts with BP and the Rio Tinto Group before being appointed in 1987 as special adviser to the then Home Secretary Douglas Hurd.

[13] Lidington was also criticised by local newspaper the Bucks Herald for claiming £115,891 in expenses in one year, almost double his salary.

In November 2013, Lidington was criticised in an editorial of the local newspaper the Bucks Herald after he abstained on votes on the HS2 rail project which will run through his constituency.

Under Prime Minister Theresa May, Lidington was appointed Leader of the House of Commons and Lord President of the Council.

[7] His appointment was criticised due to his record on LGBT rights, having opposed scrapping the ban on 'promotion of homosexuality' in schools, as well as civil partnerships.

[19] Several media outlets subsequently referred to Lidington as Theresa May's de facto Deputy Prime Minister and a candidate for her succession.

[24] Writing in his local newspaper, the Bucks Herald, on 30 October 2019, Lidington said he was not planning to seek re-election at the next general election.
