Traditional gun salutes in London will mark the Queen's 88th Birthday today. A Buckingham Palace spokesperson has confirmed she will spend the day privately at Windsor Castle.
She will be honoured publicly when the King's Troop Royal Horse Artillery fires a 41-gun salute from Green Park in central London at midday, using six 13-pounder First World War guns drawn by 71 horses.
An hour later the Honourable Artillery Company will fire a 62 Gun royal salute from Tower Wharf by the Tower of London.
The Queen has two birthdays - the day of her actual birth today, and her official one in June, which is celebrated with the Trooping of the Colour parade.
