Sir Philip Antony Fyson Buck QC (19 December 1928 – 6 October 2003) was a British Conservative politician.
He then trained as a barrister and was called to the bar by the Inner Temple in 1954, becoming a prominent criminal lawyer and a Queen's Counsel in 1974.
A strong supporter of the modernising Conservatism championed by Edward Heath, Buck served as the Under-Secretary for Defence from 1972 to 1974 with responsibility for the Royal Navy,[5] but his fortunes declined when Heath lost the election in 1974, and he managed the unsuccessful leadership campaign for his old friend Geoffrey Howe.
Nevertheless, he remained a perceptive observer of defence policy, opposing the closure of Colchester's military hospital and other cuts.
In 1994, tabloid newspaper reports of a relationship between his second wife, Bienvenida (née Perez-Blanco) [es] and Marshal of the Royal Air Force Sir Peter Harding, were followed by Harding's resignation as Chief of the Defence Staff.
