For the first time in 70 years the Queen won't receive the Trooping the Colour salute, report says

• Queen Elizabeth II won't receive the Trooping of the Colour salute, according to The Sunday Times.
• The outlet reports that Prince Charles, Prince William, and Princess Anne will stand in for the Queen.

Queen Elizabeth II won't receive the Trooping of the Colour salute for the first time in 70 years, The Sunday Times reports.

Prince Charles, Prince William, and Princess Anne will take the military salute at the Horse Guards Parade, according to the outlet. The Sunday Times reported that the Queen, 96, will hopefully attend part of the event, but the ceremony is being modified for her comfort.

Representatives for Buckingham Palace did not immediately respond to Insider's request for comment.

The queen was photographed using a walking stick earlier this month after "episodic mobility problems" caused her to miss the State Opening of Parliament for the first time in 59 years, BBC reported. Charles stepped in to deliver the Queen's speech.

The Trooping of the Colour is a historic event for the Queen, who is the head of the armed forces. For almost 300 years, the ceremony has marked the official birthday of the British Sovereign, according to the official royal website. This year's ceremony also launches the beginning of four days of national celebrations for the Queen's Platinum Jubilee.

According to The Sunday Times, one of the tentative plans includes the Queen traveling by carriage from Buckingham Palace to inspect the troops. She would then rest while Charles, William, and Anne represented her at the parade. The royal would make an appearance at the palace for the traditional balcony moment with members of her family.

Her Majesty would have less involvement in another plan, the outlet says, only appearing on the balcony at the end of the ceremony.

The only other time the Queen did not attend the Trooping of the Colour for the royal salute was in 1955 when the event was canceled due to a national rail strike, Hello Magazine previously reported.

Insider's Mikhaila Friel reported that Queen Elizabeth broke a decades-old tradition by excluding non-working royals from appearances on the Buckingham Palace balcony at the Trooping the Colour parade. In previous years, the royal family would gather to watch a flyover of the Royal Air Force from the balcony.

Prince Harry and Meghan Markle will be excluded from the balcony after stepping down as senior royals in 2020. A spokesperson for Harry and Meghan confirmed to Insider that the couple will travel with their children to London to celebrate the Queen's Jubilee.

Prince Andrew, Princess Beatrice, and Princess Eugenie will also be missing from the balcony this year.

Five people were injured at a Trooping the Colour rehearsal Saturday when parts of the spectator stand collapsed, BBC reports. The outlet said that two people were taken to major trauma units, while three were treated at the scene.
