Prince Philip has been admitted to hospital for an exploratory operation, Buckingham Palace says.

The Duke of Edinburgh, who will be 92 on 10 June, was admitted to the London Clinic "following abdominal investigations" and is expected to stay in the hospital for up to two weeks.

The BBC's Nicholas Witchell says he was unwell on Monday night but was reportedly in good spirits at a garden party on Thursday.
