Duke of Edinburgh celebrates 90th birthday

The Queen has conferred the title and office of Lord High Admiral of the Navy on HRH Duke of Edinburgh, on the occasion of his 90th birthday.

But it was just a normal day at the office for Prince Philip on his birthday, as he spent the morning hosting a charity event at Buckingham Palace.

Speaking earlier to the BBC, he said it might, finally, be time to start slowing down, as he 'reckons he's done his bit'.
