The Queen is being joined by members of her family at Windsor Castle for the celebration of her 93rd birthday.
The occasion of the monarch’s birthday coincides with Easter Sunday this year meaning it is a double celebration for The Queen who is Head of the Church of England.
Members of The Royal Family have joined Her Majesty in Windsor for the occasion.
It is expected that they will attend church in the morning to mark the most important event in the Christian calendar.
Meanwhile, at Buckingham Palace, the Band of the Irish Guards will perform a rendition of Happy Birthday during the Changing of the Guard ceremony.
Gun Salutes never take place on a Sunday. As such, the mark of respect has been postponed by a day.
On Monday, the King’s Troop Royal Horse Artillery will stage a 41 Gun Royal Salute at noon in Hyde Park.
A further 62-gun salute will also be performed by the Honourable Artillery Company at the Tower of London at 1pm.
