George Ivar Louis Mountbatten, 4th Marquess of Milford Haven (born 6 June 1961), styled Earl of Medina before 1970, is a British peer and businessman.



Lord Milford Haven is the elder son of the 3rd Marquess of Milford Haven and Janet Mercedes Bryce, the older brother of Lord Ivar Mountbatten and a descendant of Catherine the Great and Alexander Pushkin. At the death of his father on 14 April 1970, he became the 4th Marquess of Milford Haven and head of the House of Mountbatten. He is second cousin to Charles, Prince of Wales through both of their fathers.

Lord Milford Haven married first Sarah Georgina Walker (born London, Middlesex, 17 November 1961/2), former wife of Andreas Antoniou (married 1985; divorced 1987), daughter of George Alfred Walker and Jean Maureen (née Hatton), in London on 8 March 1989. The couple were divorced on 27 February 1996 and she married in June 2016 Michael Spencer, Lord Spencer of Alresford. They had two children:

Lord Milford Haven subsequently married Clare Husted Steel (born Manhattan, New York, New York County, New York, 2 September 1960) at Coatue Point, Nantucket, Nantucket County, Massachusetts, on 20 August 1997, without issue.


In 2000, he founded uSwitch, a website which helps consumers compare and change suppliers of various services. The company was sold to the American media firm E. W. Scripps in March 2006 for around £210 million ($400 million).[2]

He plays polo, and Julian Hipwood has coached his teams.[3] He won the Queen's Cup with the Broncos team in 1988 and reached the 2006 final.[4]
