The Queen marks her 91st birthday today - her "real" birthday, as the monarch traditionally has two.
Celebrations will be more subdued than last year, when her 90th was marked by national festivities.
But she can still expect royal gun salutes from the King's Troop Royal Horse Artillery and the Honourable Artillery Company at midday.
The Queen is thought to be at Windsor Castle, where she traditionally spends a month-long residence, known as Easter Court.
Her "official" birthday - marked by the Trooping the Colour ceremony - takes place in the summer.
