Sir (William) Marcus John Worsley, 5th Baronet, (6 April 1925 – 18 December 2012), was a British Conservative Party politician. He served as a Member of Parliament in four parliaments between 1959 and 1974, and served as High Sheriff and Lord Lieutenant for North Yorkshire. Biography Worsley was born in the family home of Hovingham Hall, near Malton, North Yorkshire, the eldest son of Colonel Sir William Worsley, 4th Baronet, and Joyce Morgan Brunner. He was the eldest brother of Katharine, Duchess of Kent. He was educated at Eton. After conscripted service in the Green Howards, which included a secondment to the Royal West African Frontier Force, he graduated as BA from New College, Oxford, in 1949. Worsley was a Councillor on Malton Rural District Council from 1955, serving as vice-chairman in 1965. He was an unsuccessful candidate at the 1955 election for the marginal constituency of Keighley in West Yorkshire. However, at the 1959 election he defeated the sitting Labour Member of Parliament (MP) Charles Hobson, taking the seat with a majority of only 170. At the 1964 general election, he lost his Keighley seat to Labour's John Binns, but for the 1966 election he was selected as candidate for the safe Conservative seat of Chelsea in west London. He held that seat for three Parliaments, before retiring at the October 1974 general election. He served as the Second Church Estates Commissioner, the church of England's link to the House of Commons, from 1970 to 1974. In 1973, when he inherited the title and estate, he moved back into Hovingham Hall and managed the estate. In 1982 he was appointed High Sheriff of North Yorkshire. In 1978 he was appointed a Deputy Lieutenant for North Yorkshire, serving as Lord Lieutenant from 1987 to 1999. He also served the county as High Sheriff from 1982 to 1983. He was appointed a Knight of Justice of the Order of Saint John in 1987.
