Barbara Castle, Baroness Castle of Blackburn

Barbara Anne Castle, Baroness Castle of Blackburn, PC, GCOT was a British Labour Party politician who was the Member of Parliament for Blackburn from 1945 to 1979, making her the longestserving female MP in the history of the House of Commons, until that record was broken in 2007 by Gwyneth Dunwoody. She later became the Member of the European Parliament for Greater Manchester from 1979 to 1989. One of the most significant Labour Party politicians of the 20th century, she served in the Cabinet under Prime Minister Harold Wilson in a number of roles, including as Secretary of State for Employment, Secretary of State for Social Services, and First Secretary of State.

The youngest of three children, she was born in Chesterfield to Frank and Annie Betts, and was brought up in Pontefract and Bradford. Castle was first introduced to socialist politics and beliefs from a young age, growing up in a politically active home. Her older sister, Marjorie, later became a pioneer of the Inner London Education Authority, while her brother Jimmie engaged in field work with Oxfam in Nigeria. She joined the Labour Party as a teenager.
