The Duke of York is also on his way to the Queen’s Scottish home, sources say. Family members are rushing to be by the side of Queen Elizabeth II after doctors said they were concerned about the health of the 96-year-old monarch, saying she should remain under medical supervision.
The Queen, Britain’s longest-reigning sovereign and the world’s oldest monarch, has been suffering from what Buckingham Palace has called “episodic mobility problems” since the end of last year.
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.”
Camilla, the Duchess of Cornwall had been scheduled to open a new visitor centre for the Great Tapestry of Scotland in Galashiels in the Scottish Borders on Friday.
The latest announcement escalates fears for the monarch’s health.
It comes after the head of state pulled out of a virtual Privy Council on Wednesday after doctors ordered her to rest.
Prime Minister Liz Truss said the whole country will be deeply concerned by the news from Buckingham Palace, adding her thoughts and the thoughts of people across the United Kingdom are with the Queen and her family at this time.
Commons Speaker Sir Lindsay Hoyle interrupted a speech by SNP Westminster leader Ian Blackford during the energy debate to tell MPs: “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.”
Labour leader Sir Keir Starmer said he felt “deeply worried” by the news from Buckingham Palace and is hoping for the Queen’s recovery.
He 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.”
Ms Truss was on the front bench of the Commons after her first major policy intervention as Prime Minister when she received the concerning news about the Queen’s health.
The initial indication something was wrong came as Chancellor of the Duchy of Lancaster, Nadhim Zahawi, came into the Chamber, sat down next to the Prime Minister and began urgently speaking to her while she was listening to Sir Keir Starmer’s response to her energy statement.
Sir Keir, too, was passed a note by his deputy Angela Rayner, with Commons Speaker Sir Lindsay Hoyle also handed a piece of paper updating him about the developing situation.
Labour MP Chris Bryant spotted something was wrong about 20 minutes before Buckingham Palace made its announcement, tweeting: “Something odd is going on in the Commons. Zahawi briefing pm urgently.”
In the Commons, the debate about the Government’s energy policy carried on, but MPs’ thoughts were elsewhere. Rhondda MP Mr Bryant said: “The Commons feels chilly and sombre, as if the blood has been drained from its cheeks. We wish Her Majesty and her family well.”
Last October, the Queen spent a night in hospital and she has been forced to cut back on her public engagements since then.
She had been pictured appointing Ms Truss as the new prime minister at Balmoral on Tuesday.
A palace source said immediate family members had been informed and played down speculation the monarch had suffered a fall.
The Queen has been head of state in Britain and more than a dozen other countries since 1952. Earlier this year she celebrated her 70th year on the throne.
