Queen Elizabeth II celebrates her 91st birthday today, and after the nationwide festivities for her 90th birthday last year, this year's festivities will be a lot more subdued.
But the day won't pass without a little pomp and circumstance - so here's what's on the agenda:
The occasion will be marked publicly by gun salutes in various locations in central London at midday:
- a 41 gun salute in Hyde Park
- a 21 gun salute in Windsor Great Park
- a 62 gun salute at the Tower of London
Trooping the Colour
This is also known as the Queen's Birthday Parade, and takes place a couple of months after her actual birthday. Although her actual birth date is 21 April, sovereigns' birthdays are traditionally celebrated officially in the summer months. This year the big event takes place on Saturday 17 June, with more than 1,400 officers and men and approximately 400 musicians from the Massed Bands of the Household Division taking part.
