William Sefton, Baron Sefton of Garston

William Henry Sefton, Baron Sefton of Garston (5 August 1915 – 9 September 2001) was a British Labour Party politician.

Born in Garston, Liverpool to a working-class family in 1915, Sefton was a plumber by trade. He became a trade unionist and joined the Labour Party in 1949. In 1953, he was elected to the Liverpool City Council. He was leader of the Liverpool City Council from 1964 to 1974 and Chairman of the Merseyside County Council from 1974 to 1977.

He stood in the 1959 general election as the Labour candidate for Liverpool Toxteth, but lost. He remarked afterward that "I don't think I could stand parliament, even being a minister. The best thing you could do is blow the place up."

Sefton married Phyllis Kerr in 1940; she died in 1991. He later married Evelyn Pimlett in 2000. He died on 9 September 2001, aged 86.
