Sir Wayne David (born 1 July 1957) is a Welsh politician who served as Member of Parliament (MP) for Caerphilly from 2001 to 2024.

David taught history at the Brynteg Comprehensive School, Bridgend from 1983 to 1985, when he left to work for the Workers' Educational Association.

In 2005, he was appointed as Parliamentary Private Secretary (PPS) to the Ministry of Defence team and then subsequently to Adam Ingram, Minister of State for the Armed Forces.

He resigned as a PPS on 6 September 2006, along with a number of others, citing Prime Minister Tony Blair's refusal to name a departure date.

At the 2005 general election, David was re-elected as MP for Caerphilly, with a decreased vote share of 56.6% and an increased majority of 15,359.

[6][7] After Gordon Brown became Prime Minister, David was appointed as an Assistant Whip to the Department for Work and Pensions and Wales Office in July 2007.

David was re-appointed to the roles by Labour Leader Jeremy Corbyn in September 2015, but resigned the following June after losing confidence in his leadership.

[13] David re-joined the Corbyn's front bench in October 2016 as Shadow Armed Forces and Defence Procurement Minister.

[16][17] David briefly departed the front bench from January until April 2020, when he became Shadow Middle East and North Africa Minister.
