Queen Elizabeth II will appoint a new prime minister at her Balmoral home in Scotland-the first time Her Majesty will do so. As this adds to the growing concern about the monarch's health issues, the public gets more worried after knowing Prince Charles is paying his mom "highly unusual visits."

Queen Elizabeth is reportedly facing mobility issues. She used to have audiences when appointing new premiers at Buckingham Palace, but things are different today.

In an interview on "7News," via Express, Europe correspondent Sarah Greenhalgh revealed this decision to hold this important event at Balmoral is to "provide certainty for the new prime minister's diary." It's said to be the first time in her 70 years of reign that she would hold this historic duty away from Buckingham Palace, raising more concerns about her health.

She continued that no one wanted to have any last-minute changes should there something happen to Queen Elizabeth's condition. However, Greenhalgh stressed that the leader of 14 Commonwealth realms isn't sick, but given her age of 96 and mobility issues, there are "renewed concerns" about her health.

These concerns grow more after several reports claim that Prince Charles is making "highly unusual daily visits" to the Queen. Greenhalgh explained that though they're mother and son, this thing doesn't usually happen. It is also said that Prince Andrew has been staying with his mother at Balmoral, where she usually spends most of her summers.

In addition, Greenhalgh noted that Queen Elizabeth has been using her walking stick a lot throughout the year. News.com.au added that there's a growing concern about the head of state's health since her husband, Prince Philip, died in April 2021.

After that, she was forced to pull out of the Remembrance Day service in November last year due to a reported sprained back. She was then required to isolate herself after testing positive for COVID-19, which she successfully triumphed. She even held meetings virtually.

Aside from these changes, she also pulled out of a series of events that came with her Platinum Jubilee celebrations in June, like the Service of Thanksgiving at St. Paul's Cathedral and the Epsom Derby.

She's also seen using a cane and buggy to help her move while dealing with her "episodic mobility" issues. Despite these concerns, Buckingham Palace assured the public that there's nothing to worry about, per Woman and Home.

The change in appointing the new prime minister is just made in line with adapting Queen Elizabeth's schedule for her comfort.
