The Duke of Edinburgh has left King Edward VII's hospital in central London, having been treated for a pre-existing condition.
Prince Philip, who is 98, left the hospital after four nights this morning - Buckingham Palace stating that he has returned to Sandringham, where he is expected to spend Christmas with the Queen.
He got into a car in a secluded street behind the hospital and was sitting in the front passenger seat.
Multiple police stood guard around the hospital as well as royal protection officers.
The admission to the private hospital was announced last Friday, a Buckingham Palace statement assuring the public the visit was a "precautionary measure, on the advice of His Royal Highness' Doctor."
Now, leaving the building on the morning of Christmas Eve, a new statement has been released by Royal Communications:
"The Duke of Edinburgh has today left hospital after being discharged by his Doctor and is now back at Sandringham.
"His Royal Highness would like to thank everyone who sent their good wishes."
