Prince Philip has left Papworth Hospital, near Cambridge, where he spent four nights after being treated for a blocked artery.

The 90-year-old Duke of Edinburgh was flown there on Friday after experiencing chest pains while at Sandringham.

Surgeons at the world-renowned heart hospital inserted a stent, or small tub, ,into the blocked artery to open it up and help restore the flow of blood.

Over the four days he was visited by The Queen, Princess Anne, Prince Charles and Camilla as well as his grandchildren, including Prince Harry and the Duke and Duchess of Cambridge.

Prince Philip stepped down from being Chancellor of the University of Cambridge after more than 30 years in the post earlier this year.
