One of the annual events celebrated at such an occasion is the Trooping the Colour parade.
The parade marks the Queen’s official birthday, and this year coincides with celebrating the monarch’s 70 years on the throne.
The official date of Her Majesty’s jubilee is February 6, but Platinum Jubilee celebrations were held off until her official birthday weekend in June, as 6 February also marks the anniversary of her father’s death as she ascended the throne when King George VI died in 1952.
Not only is this year’s Trooping the Colour parade doubly special due to the Platinum Jubilee celebrations, it also marks the first time in two years that the parade will return to its former, pre-pandemic glory.
Last year, much like in 2020, the parade had to be cancelled in its usual form due to the ongoing coronavirus pandemic and the Queen saw a pared-back version at the Quadrangle of Windsor Castle.
Last year the monarch was joined by her cousin the Duke of Kent, for her first Trooping the Colour following the death of Prince Philip, who would have turned 100 just two days before, on 10 June.
This year however, the Queen is set to be joined by all of the senior working members of the Royal Family, including the Cambridges and their three children, although Prince Harry, Meghan Markle and their two children Archie, 3, and Lilibet, 11 months, won’t be joining Her Majesty on the balcony.
"After careful consideration, The Queen has decided this year’s traditional Trooping the Colour balcony appearance on Thursday 2 June will be limited to Her Majesty and those members of the Royal Family who are currently undertaking official public duties on behalf of The Queen," a Buckingham Palace spokesperson said.
This means those invited to join her on the balcony will be limited to The Prince of Wales and The Duchess of Cornwall, The Duke and Duchess of Cambridge and their children, The Earl and Countess of Wessex and their children, The Princess Royal and Admiral Sir Timothy Laurence, The Duke and Duchess of Gloucester, The Duke of Kent, and Princess Alexandra.
They then congregate on the famous Buckingham Palace balcony to watch the RAF fly-past.
