The Queen is under medical supervision at Balmoral after doctors became concerned for her health, Buckingham Palace has said.
“Following further evaluation this morning, the Queen’s doctors are concerned for Her Majesty’s health and have recommended she remain under medical supervision,” a statement said.
“The Queen remains comfortable and at Balmoral.”
The Duchess of Cornwall has also travelled Balmoral, and the Duke of Cambridge is reportedly on his way to meet her.
Buckingham Palace said in a statement: “Following further evaluation this morning, The Queen’s doctors are concerned for Her Majesty’s health and have recommended she remain under medical supervision.
“The Queen remains comfortable and at Balmoral.”
The monarch remains at Balmoral, after being advised to cancel arrangements for the Privy Council virtually on Wednesday evening, during which Ms Truss would have taken her oath as First Lord of the Treasury and her new cabinet ministers would have been sworn into their roles.
The Privy Council is a formal body, mainly made up of senior politicians, which advises the Queen.
“This means that the Privy Council meeting that had been due to take place this evening will be rearranged.”
Ms Truss said the whole country would be “deeply concerned” by the news, adding her thoughts were with the monarch and her family.
Meanwhile Commons Speaker Sir Lindsay Hoyle interrupted a debate on energy bills in the House of Commons to update MPs about the Queen’s health.
He cut short SNP Westminster leader Ian Blackford’s speech to say: “I know I speak on behalf of the entire House when I say that we send our best wishes to Her Majesty the Queen and that she and the royal family are in our thoughts and prayers at this moment.”
He added: “If there is anything else, we will update the House accordingly.”
Leader of the opposition, Sir Keir Starmer, tweeted: “Along with the rest of the country, I am deeply worried by the news from Buckingham Palace this afternoon.
“My thoughts are with Her Majesty The Queen and her family at this time, and I join everyone across the United Kingdom in hoping for her recovery.”
Immediate family members have been told of the doctor’s decision, Sky News’ royal correspondent, Rhiannon Mills, said.
They are said to be very keen there is no further speculation – amid suggestions the Queen had suffered a fall, which are believed to be incorrect.
Mills said: “Of course, there undoubtedly is going to be concern about the Queen.
“It was only last night at six o’clock that we were informed by Buckingham Palace that the Queen had to pull out of conducting a Privy Council meeting which had been pencilled in yesterday evening.
“Last night, they said that after a full day on Tuesday, Her Majesty had accepted the doctor’s advice to rest, which had meant the Privy Council meeting that she was due to be conducting, albeit remotely from Balmoral, wasn’t able to go ahead.”
