Sir David Michael Davis is a British politician who served as Shadow Home Secretary from 2003 to 2008 and Secretary of State for Exiting the European Union from 2016 to 2018. A member of the Conservative Party, he has served as the Member of Parliament (MP) for Haltemprice and Howden, formerly Boothferry, since 1987. Davis was sworn of the Privy Council in the 1997 New Year Honours, having previously been Minister of State for Europe from 1994 to 1997.

In British politics, the Shadow Home Secretary is the person within the shadow cabinet who shadows the Home Secretary; this effectively means scrutinising government policy on home affairs including policing, national security, and matters of citizenship. The Shadow Home Secretary also formerly had responsibility for the criminal justice system and the prison service; these responsibilities are now held by the Shadow Justice Secretary. If the opposition party is elected to government, the Shadow Home Secretary often becomes the new Home Secretary, though this is not always the case. The office has been held by Labour MP Yvette Cooper since 29 November 2021.
