Duke of Edinburgh 'keen to leave hospital already'
Questions will need to be asked about the workload of the Duke of Edinburgh following treatment to unblock an artery, the BBC's Nicholas Witchell says.
Prince Philip was flown to hospital last night after suffering chest pains, where a coronary stent was fitted.
The Queen and all their children have now visited him at Papworth Hospital in Cambridgeshire.
He is now said to be keen to go back home.
