Fears grew on Thursday for British Queen Elizabeth II after Buckingham Palace said her doctors were "concerned" for her health and recommended that she remain under medical supervision.
"Following further evaluation on Thursday morning, the Queen's doctors are concerned for Her Majesty's health and have recommended she remain under medical supervision," a statement from Buckingham Palace said, reports BSS.
"The Queen remains comfortable and at Balmoral," it added.
Moments before, notes were passed to Prime Minister Liz Truss and senior members of her team in parliament, prompting them to leave the chamber.
Truss tweeted almost immediately afterwards.
"The whole country will be deeply concerned by the news from Buckingham Palace this lunchtime," she added.
"My thoughts -- and the thoughts of people across our United Kingdom -- are with Her Majesty the Queen and her family at this time."
Heir to the throne Prince Charles, 73, and his eldest son, Prince William, 40, were heading to Scotland, according to their Clarence House and Kensington Palace offices.
