Royal family members gather by Queen Elizabeth's side as health concerns swirl

Queen Elizabeth II is under medical supervision at Balmoral Castle in Scotland after her doctors became worried about her health.

Members of the royal family are already by the queen's bedside in Balmoral — and others are on their way —

after her doctors placed the 96-year-old monarch under medical supervision Thursday, the British media, including the BBC and The Guardian, reported.

"Following further evaluation this morning, the Queen's doctors are concerned for Her Majesty's health and have recommended she remain under medical supervision," Buckingham Palace said in a statement.

The BBC reported that the statement — and the fact that family members are traveling to her — marks a significant change in her situation.

Elizabeth and her late husband Prince Phillip, who died in April 2021, have four children:

Prince Charles, Princess Anne, Prince Andrew and Prince Edward. They also have eight grandchildren and 12 great-grandchildren.

Charles, the queen's oldest son and heir to the throne, is already by his mother's side, as is his wife, Camilla.

Prince William, Charles' son and second in line for the throne, also has arrived at Balmoral .

His wife, Kate, the Duchess of Cambridge, stayed behind in Windsor, the BBC reported.
