David Davis (born December 23, 1948) is a British politician, and Conservative MP for Haltemprice and Howden.

He has graduated in computer science and molecular science from the University of Warwick in 1971, and then mainly worked for Tate and Lyle.

He contested the 2001 election for the leadership of the Conservative party, but came last. He used to be chairman of the Conservative Party but was sacked in 2002 by Iain Duncan Smith. He was given a new job by the long winded title of Shadow Secretary of State for the Office of the Deputy Prime Minister. After Smith was removed as Tory leader by a vote of no confidence, he surprised commentators by quickly announcing that he would not stand again for the leadership, and leant his support to Michael Howard instead. He was rewarded for this by being made Shadow Secretary of State for the Home Department.

Not to be confused with Welsh Assembly Member, David Davies.
