Thousands of people gathered in central London to watch the celebration of the Queen's official birthday,
Trooping the Colour.
The ceremony was performed by the Household Division - Foot Guards and Household Cavalry.

Captain Ben Sempala-Ntege, 27, of the Royal Horse Artillery, was left section commander of the King's Troop.
Among the guards was Anton Branchflower of the Irish Guards, at 20 the youngest member of the Army to have been awarded the Military Cross.
He received the honour for shooting an Iraqi soldier who was about to throw a grenade.
At lunchtime, the Queen and other members of the Royal Family appeared on the balcony of Buckingham Palace to greet the crowds and watch an RAF fly-past.
