At 96, Prince Philip has called it a day. Being Britain, it rained on his final parade but it didn't appear to dampen his spirits.
In raincoat and bowler hat, the Duke of Edinburgh even cracked a joke as he inspected an honour guard assembled to mark the end of a series of endurance feats by the Royal Marines.
Prince Philip, Captain General of the elite commando force, met two extremely fit young troops who ran 2645km in 100 days to raise funds for charity.
"You should all be locked up, " the duke quipped, which by his standards was an extremely restrained remark. His highlights reel includes plenty of both off-colour and witty asides which made him the most gaffe-prone - and interesting - member of the Royal Family.
Britain had mileage out of the duke. Buckingham Palace calculated that his last official event was his 22,219th solo engagement since his wife became Queen in 1952. Up till his retirement he had spent 52 days on public duty.
