Since last year, the 96-year-old monarch has been experiencing mobility difficulties.

On Saturday, the Queen will not attend the popular Highland Games Braemar Gathering in Scotland.

The decision was made for the comfort of Her Majesty, who has suffered from mobility issues since last year.

On Saturday, the Prince of Wales will join spectators at the gathering, which draws spectators from around the world to watch competitors in the caber toss, hammer throw, and tug of war.

It follows the Queen’s announcement that, for the first time in her reign, she will appoint the new prime minister at Balmoral, in what has been described as a “huge break with tradition.”

On Tuesday, September 6, the monarch will meet either Liz Truss or Rishi Sunak, a day after one of them is announced as Boris Johnson’s replacement and given the keys to 10 Downing Street.

Typically, new prime ministers are appointed at either Buckingham Palace or Windsor Castle.

Whoever wins the Conservative leadership contest will become the 15th British prime minister appointed by the Queen, who appointed Winston Churchill in 1951.

This year, Her Majesty celebrated her Platinum Jubilee, but she skipped several events commemorating her historic 70 years on the throne.

After experiencing discomfort during the first day of Jubilee events, including a birthday parade and flypast, the guest of honor “reluctantly” canceled plans to attend a thanksgiving service at St Paul’s Cathedral.

Concerns about the Queen’s health are growing, as she is frequently pictured sitting or using a walking stick.

Earlier in May, the Queen missed the State Opening of Parliament for the first time in 59 years due to “episodic mobility issues” prescribed by her physician.

Charles, 73, read Her Majesty’s speech while he and the Duke of Cambridge jointly opened the new session of Parliament as Counsellors of State on the Queen’s behalf.

The monarch was also forced to miss her first Royal Ascot since her June coronation.

This year, she declined to attend the annual Easter Sunday service at St. George’s Chapel in Windsor.

Instead, William and Kate led the royals at the annual royal celebration.
