Thomas Williams (UK politician)

Sir William Thomas Williams, QC (22 September 1915 – 28 February 1986) was a British Labour Co-operative politician.

Williams was educated at University College, Cardiff and St Catherine's College, Oxford. He was President of the South Wales University Students' Union in 1939. He was a Baptist minister and a chaplain with the Royal Air Force for returned prisoners of war. He became a barrister, called to the bar by Lincoln's Inn, and a Queen's Counsel, and was bursar and a tutor at Manchester College, Oxford.

Williams was Member of Parliament (MP) for Hammersmith South from a 1949 by-election to 1955, Baron's Court from 1955 to 1959, and Warrington from a 1961 by-election. Williams served as parliamentary private secretary to the Attorney-General from 1964. In 1969, Williams was appointed by the then-East Pakistan based Awami League, one of Bangladesh's main political factions since independence in 1971, to represent Pakistani and later-Bangladeshi politician Sheikh Mujibur Rahman in the Agartala Conspiracy Case. The military junta of Gen. Ayub Khan did not allow Williams to represent Rahman, citing domestic security and interference in sovereign matters.
