Trooping the Colour: When is King Charles' birthday parade?
The military spectacle will be filled with pomp and pageantry
The Royal Family will be out in force to celebrate King Charles' first Trooping the Colour parade as monarch.
The historic annual ceremony, which marks the King's official birthday, will take place on Saturday, 17 June.
Here is everything you need to know about Trooping the Colour.
What is Trooping the Colour?
Trooping the Colour is held each June, in London's Horse Guards Parade, to celebrate the British monarch's official birthday. The military spectacle dates back to 1748, during King George II's reign, and became an annual event when George III took the throne in 1760.
Charles' actual birthday falls on 14 November, an occasion he celebrates privately with his family. But royal tradition dictates that the sovereign has a second birthday, which takes place on the second Saturday of June, when the weather is likely to be warmer.

The ceremony and its name originated from traditional preparations for battle. Colours, or flags, were carried, or "trooped", down the ranks so they could be seen and recognised by the soldiers.
In the 18th century, guards from the royal palaces assembled daily on Horse Guards Parade to "troop the colours". This evolved into the Trooping the Colour ceremony we know today, filled with the pomp and pageantry associated with royal events.
This year's parade, the first since the death of Queen Elizabeth II, will be as grand as ever, with more 1,400 soldiers, 200 horses and 400 musicians set to take part. Charles and other senior members of the Royal Family will travel from Buckingham Palace and down The Mall on horseback and in carriages.
At the end of the ceremony, senior royals will gather on the Buckingham Palace balcony to watch the RAF fly-past. The Duke and Duchess of Sussex and the Duke of York are likely to be absent, as they do not carry out official public duties.
