Jacqueline Jill "Jacqui" Smith (born 3 November 1962) is a British Labour Party politician who previously served as the first female Home Secretary, and has been Member of Parliament for Redditch since 1997. She was made a Member of the Privy Council in 2003. Smith is also the third woman to hold one of the Great Offices of State — after Margaret Thatcher (Prime Minister) and Margaret Beckett (Foreign Secretary).

Smith was considered by some to be a controversial Home Secretary. She is currently one of the MPs under investigation by the parliamentary commissioner for standards over inappropriate expense claims. On 2 June 2009, it emerged she would stand down at the forthcoming Cabinet reshuffle on 5 June 2009.

Born in Malvern, Worcestershire, Smith attended Dyson Perrins High School in Malvern. Her parents were teachers. Her local MP, Conservative backbencher Sir Michael Spicer, recalled in Parliament in 2003 how he had first met her when he was addressing the sixth form at The Chase School, where Smith's mother was a teacher. "So great was my eloquence that she immediately rushed off and joined the Labour Party." Smith went on to study for a Bachelor of Arts in Philosophy, Politics and Economics at Hertford College, Oxford. After Oxford, she studied for a PGCE at Worcester College of Higher Education.
