Melville Richard John Guest OBE (born 18 November 1943) is a British former diplomat and first-class cricketer.
He was born in what was then Salisbury, Southern Rhodesia, two weeks after the death of his father, Ernest Melville Charles Guest, a RAF pilot who was killed in action over the English Channel.
In the Varsity Match of 1965, after Oxford lost three early wickets, Guest and his fellow batsman Mike Groves were barracked by the crowd for slow scoring, with 13 consecutive maiden overs bowled by the two Cambridge spinners.
After a tour of duty in Paris, he temporarily left the FCO and was managing director of Lucas France from 1980 to 1985.
[6][7] In the same year he received the official Commendation of the Japanese Foreign Minister for services to the UK's relations with Japan.
