Queen Elizabeth's traditional welcome to the Balmoral Castle was canceled, sparking new health concerns.

The 96-year-old had been due to attend the ceremony in Scotland Monday. It was recently canceled and replaced with a “small, private event," reported Mirror. It is understood that until just days ago she was still intending to attend the event where usually, she would inspect a Guard of Honor from Balaklava Company, 5th Battalion, The Royal ­Regiment of Scotland. Apart from the pandemic, it is the first time in decades, that she did not greet well-wishers at the gates to mark the beginning of her annual holiday.

A source said that the traditional welcome to Balmoral is "normally cemented in the Queen’s calendar and something Her Majesty really enjoys, being able to greet locals who travel to see her." The insider added that it was a "bitter disappointment the ceremony" could not take place in its "traditional form.”

Some sources suggested that the alternative plan was “very much a sign of things to come."

Buckingham Palace insisted that the private ceremony was “in line with adapting Her Majesty’s schedule for her comfort."

Since arriving in Scotland on July 21 for summer break, the Queen has been staying at Craigowan Lodge on the Balmoral estate, according to Geo News.

She has been experiencing mobility issues since autumn 2021, and she has frequently used a walking stick and shortened some engagements, including at the Platinum Jubilee in June, reported Express.

Amid her health condition, many have commented on her mental state and whether she is fit to continue in her role. Royal commentator Richard Fitzwilliams is among those who believe she is more than capable, and has displayed signs of clear decision-making.

In the event the Sovereign becomes incapacitated or is absent, a Regent can rule on behalf of the monarch. Claims that the Queen's son Prince Charles is now a de-facto Prince Regent emerged earlier this year. This popped up as the future King carried out duties on his mother’s behalf. Charles took on many responsibilities including the State Opening of Parliament in May. He carried it out the engament along with his elder son Prince William.
