Britain's Queen Elizabeth is set to host a dinner party in honour of billionaire racehorse owner the Aga Khan. Senior members of the British royal family will attend the queen's official residence Buckingham Palace for dinner on Monday

(14.07.08) in honour of the monarch's long-term friend. The queen, 82, and the Aga Khan, 71, are both huge fans of horse racing and have previously watched the sport together at Royal Ascot. The Aga Khan was the owner of Shergar, the Derby-winning racehorse who was kidnapped from his Irish stud farm in 1983 and never seen again. He is also the Imam of the world's 15 million Shia Ismaili Muslims and a direct descendant of the Prophet Muhammad. Last year, he celebrated the 50th anniversary of his succession to the title held by his grandfather. The Aga Khan is coming to the end of a seven-day visit to the UK held to mark the milestone.
