Troops have been marking the 70th anniversary of the Queen's accession to the throne today with gun salutes around the UK.
As Her Majesty's Accession Day Platinum Jubilee fell on a Sunday, tradition dictates that the royal salute is not fired until the following day.
This afternoon, the King's Troop Royal Horse Artillery fired a 42-gun salute from Green Park at 12pm, followed by a 62-gun salute by the Honourable Artillery Company, the City of London's Reserve Army Regiment, at the Tower of London.
A 21-gun salute was also fired from Edinburgh Castle.
A royal salute usually features 21 rounds fired, but this is increased to 41 if it takes place in a royal park or residence.
If a gun salute takes place at the Tower of London, there are an extra 21 rounds fired for City of London citizens to show respect to the monarch, bringing the grand total of rounds to 62 from that location.
Personnel part of today's events will feature both regular and reservist soldiers.
Ahead of King's Troops arrival in Green Park, the Band of the Grenadier Guards performed celebratory music near the firing position.
Seventy-one horses and six World War One-era gun carriages from King's Troop made their way from Wellington Barracks, past Buckingham Palace into Green Park to conduct the salute.
Later, Honourable Artillery Company set off from their Armoury House Barracks for the Tower of London, with their guns (the regiment's colours) in tow, with three L118 Ceremonial Light Guns firing 62 rounds across the River Thames.
