UK- Queen Elizabeth II is under medical supervision at Balmoral Castle in Scotland, a statement from Buckingham Palace says.
On Wednesday evening, she abruptly canceled a virtual meeting with members of her Privy Council after her doctors advised her to rest.
Her doctors are concerned for her health, following further evaluation on Thursday morning, the statement says.
Prince William, the Queen’s eldest grandson and second in line to the throne, is on his way there, while his wife Kate, Duchess of Cambridge, has remained in Windsor as her children are on their first full day at their new school.
Prince William’s brother, Prince Harry, and his wife Meghan had been in the UK in recent days for engagements, and are now known to be travelling to Scotland too.
Prime Minister Liz Truss says “the whole country will be deeply concerned by the news”
The Archbishop of Canterbury said he was sending his prayers and the first ministers of Scotland and Wales joined well-wishers in sending their thoughts.
Elizabeth II (96) is the Queen of the United Kingdom and 14 other Commonwealth realms.
