Reginald Ernest Prentice, Baron Prentice, PC (16 July 1923 – 18 January 2001)[1] was a British politician who held ministerial office in both Labour and Conservative Party governments. He was the most senior Labour figure ever to defect to the Conservative Party.
He was a councillor for Whitehorse Manor in the then-County Borough of Croydon from 1949, having stood unsuccessfully in Thornton Heath ward in 1947. He served on the Housing, Libraries, Planning & Development, Water and Reconstruction Committees.
In the 1971 Shadow Cabinet election, Prentice just missed out on being elected, finishing in 13th place in the ballot for 12 available places. However, in April 1972 the resignations from the shadow cabinet of Harold Lever and George Thomson saw Prentice and 14th placed candidate John Silkin join the body in their place. At the next shadow cabinet election, Prentice topped the poll and he was again re-elected in 1973, this time finishing in third place.[2]
When Labour regained power, he was Secretary of State for Education and Science between 1974 and 1975, subsequently becoming Minister for Overseas Development with a seat in the cabinet until 1976.
A biography, which provides an in-depth account of Prentice's party-political transition during the 1970s, was published in 2015: Geoff Horn, Crossing the floor: Reg Prentice and the crisis of British social democracy.[4]
