Salutes will take place in locations across the country, though members of the public have been encouraged to observe from home
Gun salutes will take place across the UK on Saturday to mark the death of Prince Philip.
The Duke of Edinburgh died aged 99 on Friday, a statement from the Royal Family confirmed.
From midday on Saturday, some 41 rounds will be fired at various locations across the UK – including London, Cardiff, Belfast, and Edinburgh – at a rate of one shot per minute.
The same is expected to happen aboard some Royal Navy ships as a show of respect to the duke, who served as a naval officer during the second world war.
The salutes are to be broadcast live on television and online, with members of the public asked to observe them from home.
In London, the King’s Troop Royal Horse Artillery will fire at Napier Lines, Woolwich Barracks, with a similar salute carried out by the Honourable Artillery Company at the Tower of London.
Guns will also be fired at Cardiff Castle, Hillsborough Castle in Belfast and Edinburgh Castle.
A statement on the royal website said: “The tradition of Gun Salutes being fired throughout the country to mark significant national events dates back to at least the eighteenth century, and there are historical records of salutes taking place as early as the 14th century when guns and ammunition began to be adopted more widely.
“Similar gun salutes were fired to mark the death of Queen Victoria in 1901.”
Prince Philip’s death was announced shortly after midday on Friday.
A statement said: “It is with deep sorrow that Her Majesty The Queen has announced the death of her beloved husband, His Royal Highness The Prince Philip, Duke of Edinburgh.
“His Royal Highness passed away peacefully this morning at Windsor Castle.”
