William Mabane, 1st Baron Mabane

William Mabane, 1st Baron Mabane PC KBE (12 January 1895 – 16 November 1969) was a British politician.

The son of Joseph Greenwood and Margaret Mabane of Leeds, he was educated at Woodhouse Grove School and at Gonville and Caius College, Cambridge. He served in World War I with the East Yorkshire Regiment in the Near East and France. He became a businessman and merchant.

Mabane was elected Member of Parliament for Huddersfield from 1931 until losing his seat in 1945, and held office as Assistant Postmaster-General 1939, Parliamentary Secretary to the Home Department, 1940-1942, Parliamentary Secretary to the Ministry of Food from 1942-1945 and Minister of State for Foreign Affairs in 1945.

Mabane's exact party label was confused for much of his time in the Commons. His local Liberal association was affiliated to the official Liberals until 1939, but Mabane was frequently listed as being a National Liberal, which he repeatedly sought to deny, despite supporting the National Government when the official Liberals ceased to.

He was appointed a Privy Counsellor in 1944 and knighted (KBE) in 1954. He was Chairman (1960-1963) and President (1964-1966) of the British Travel Association. He was raised to the peerage as Baron Mabane in 1962, the title becoming extinct on his death.
