Queen under medical supervision and royal family heads to be by her side as doctors are ‘concerned for her health’

LONDON — Britain’s Queen Elizabeth II was placed under medical supervision Thursday as her family rushed to Scotland to be by her side after doctors became concerned for the 96-year-old monarch’s health.

“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.

It added that the nation’s much-loved figurehead “remained comfortable” at Balmoral, the castle in Scotland where she spends her summers.

Prince Charles, the heir to the throne, and his wife, Camilla, the Duchess of Cornwall, traveled to Balmoral. Prince Edward and his wife, Sophie, the Countess of Wessex, as well as Prince Andrew rushed to Balmoral by plane and were joined there by Princess Anne, who was already in Scotland, meaning all the queen’s children are present.

Prince William made the journey, but his wife, Catherine, the Duchess of Cambridge, has remained at their home in Windsor, because their children, Prince George, Princess Charlotte and Prince Louis, are on their first full day at their new school, Kensington Palace said.

Prince Harry was also traveling to Scotland but Meghan, the Duchess of Sussex was not, a spokesperson for the couple said. Meghan will remain in London, where the couple had been nearing the end of a trip to Europe.

The growing fears for the queen’s health came less than 24 hours after she canceled a meeting with the Privy Council — her formal body of advisers that includes Britain’s new leader, Liz Truss — after being advised by doctors to rest.

The queen formally appointed Truss as prime minister earlier this week at Balmoral, the first time in her 70-year reign that she had performed the ceremonial royal duty anywhere but at Buckingham Palace in London.

“The whole country will be deeply concerned by the news from Buckingham Palace this lunchtime,” Truss said on Twitter on Thursday.

“My thoughts — and the thoughts of people across our United Kingdom — are with Her Majesty The Queen and her family at this time.”
