At just 25, Hugh Richard Louis Grosvenor, who has become the 7th Duke of Westminster after the sudden death of his 64-year-old father on Tuesday, will inherit a family fortune estimated by American business magazine Forbes at about £9bn, and the ancestral seat Eaton Hall in Cheshire.
Though the third of four siblings, the duke, previously known by the honorary title Earl Grosvenor, is the only son of the late Duke of Westminster and his wife, Natalia.
Little is publicly known of the former student of countryside management at Newcastle University. His family guarded his privacy as he was growing up as heir apparent to the vast fortune, which now makes him the third wealthiest landowner in the UK, and, according to Forbes, the 68th wealthiest person in the world.
