The Earl of Dartmouth has married Diandra Douglas, ex-wife of Michael Douglas, in Gibraltar PA Images / Alamy Stock PhotoHe may have just celebrated his 76th birthday, but the Earl of Dartmouth is far from giving up on love – in fact, the grandson of the great romance novelist Dame Barbara Cartland has just walked down the aisle again to marry his second wife, 69-year-old Diandra Douglas, now the Countess of Dartmouth. The couple are said to have exchanged vows in relative secrecy earlier this month, with one friend remarking to MailOnline: ‘It was a tiny, private ceremony at the Gibraltar register office, with only one or two guests.’ Chartered accountant William Legge, the 10th Earl of Dartmouth, has strong links to Gibraltar: a former UKIP MP for south west England, he later resigned but continued to represent the area, as well as the territory of Gibraltar, as an Independent in the EU parliament.
