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. A member of the Conservative Party, he served as Chancellor of the Duchy of Lancaster and Minister for the Cabinet Office from 2018 to 2019^[1] and was frequently described as being Theresa May's de facto Deputy Prime Minister.^[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.^[4] He resigned from the government on 24 July 2019, in anticipation of the appointment of Boris Johnson as Prime Minister. He did not seek reelection in the 2019 general election.^[5]
