David Wright Miliband (born 15 July 1965) is a British Labour politician, who has been the Member of Parliament for South Shields since 2001, and is the current Secretary of State for Foreign and Commonwealth Affairs. He is the son of the late Marxist theorist Ralph Miliband. He and his younger brother Ed Miliband are the first siblings to sit in the Cabinet simultaneously since Austen and Neville Chamberlain.

Born in London, Miliband studied politics at universities both in England and the USA, and started his career as a policy analyst at the Institute for Public Policy Research. At 29, Miliband became Tony Blair's Head of Policy whilst the Labour Party was then in opposition and was a major contributor to Labour's manifesto for the 1997 general election which brought the party to power. Blair made him head of the Prime Minister's Policy Unit from 1997 to 2001, following which Miliband was elected to parliament for the north-east England seat of South Shields.

Miliband spent the next several years in various junior ministerial posts in the British Government, including at the Department for Education and Skills, before becoming Environment Secretary. His tenure in this post saw climate change consolidated as a priority for UK policymakers. On the succession of Gordon Brown as Prime Minister, Miliband was promoted to Foreign Secretary, at 41, the youngest person to hold the position in 30 years.
