Live coverage from Horse Guards Parade, London, as HM The Queen takes the salute to mark the occasion of her official birthday. For the first time in 15 years, all five regiments of Foot Guards are represented on today's parade.
Her Majesty is accompanied by HRH The Duke of Edinburgh, Colonel Grenadier Guards; HRH The Prince of Wales, Colonel Welsh Guards; HRH The Grand Duke of Luxembourg, Colonel Irish Guards

The parade is the tribute by the Household Division to their Sovereign and Colonel-in-Chief, and is the most complex and spectacular military event of the year. The Queen's Colour of the First Battalion, Irish Guards, is being trooped. The parade, by tradition, is in five parts:
The Inspection of the Line - The eight Guards and the Sovereign's Escort of the Household Cavalry are inspected by the Queen.
The Troop by the Massed Bands, Corps of Drums and Pipes and Drums of the Guards Division.
Trooping the Colour through the ranks.
The March Past by the Guards Division in slow and quick time.
The Rank Past by the Household Cavalry, at the walk and at the trot.
Music played by the MASSED MOUNTED BANDS OF THE HOUSEHOLD CAVALRY and the MASSED BANDS OF THE GUARDS DIVISION
