The Queen and other senior royals have sent messages of support to Boris Johnson for a 'full and speedy recovery' as he battles coronavirus in intensive care today.
Her Majesty said her thoughts were also with the Prime Minister's heavily pregnant fiancee Carrie Symonds and his family, who are not able to visit him at St Thomas' Hospital in central London.
It is the third time in less than 72 hours that the Queen has made a public statement about the coronavirus crisis, as the death toll jumped by a record-high of 854 in a day with 6,227 known fatalities in the UK so far.
Buckingham Palace said in a statement this afternoon: 'Earlier today the Queen sent a message to Carrie Symonds and to the Johnson family. Her Majesty said they were in her thoughts and that she wished the Prime Minister a full and speedy recovery'.
And in messages released at the same time, Prince Charles and Camilla, and Prince William and Kate Middleton, also sent their best wishes to the PM.
Millions of Britons have also been moved by Mr Johnson's health battle and some will 'clap for Boris' at 8pm tonight after he was moved to an intensive care unit as he developed breathing problems.
Others across Britain posted signs in their windows reading 'pray for Boris' and 'get well soon Boris' - but some trolls posted a series of vile social media messages including many wishing him ill and using the hashtag #ImnotaTory.

'It's the worst possible timing': Royal watchers criticise Prince Harry and Meghan for unveiling details of the Archewell charitable foundation
Prince Harry and Meghan Markle (pictured above) announced yesterday they will be launching a new foundation, named 'Archewell'
Prince Harry and Meghan Markle have today been criticised after revealing some of the details of their plans to launch a new not-for-profit foundation, with one royal watcher describing it as 'the worst possible timing'.
The couple last night said they 'look forward' to getting started with the foundation, named Archewell, which will replace their Sussex Royal brand.
But royal biographer Phil Dampier has described the reveal of the details, which came as Prime Minister Boris Johnson was moved into intensive care with coronavirus, as 'appalling timing'.
The details were revealed after the Telegraph uncovered that The Sussexes had filed paperwork to trademark Archewell in the United States last month.
The trademark covers educational material, books and downloadable articles, as well pens, pencils, paperclips and clothing items, including tops, dresses and skirts.
The couple say they were 'compelled' into making the announcement last night.
It was coincidentally revealed just hours after fans took to Twitter to launch the hashtag 'ArchieDay' to celebrate the first birthday of the couple's son, Archie Harrison Mountbatten-Windsor, with a global campaign to raise money for 'vulnerable children impacted by coronavirus'.
The Duke of Cambridge tweeted a personal message, signing it off with his initial 'W', and saying: 'Our thoughts are with the Prime Minister and his family, who like so many in the UK and around the world are affected by coronavirus. We wish him a speedy recovery at this difficult time. W.'
His father the Prince of Wales, who has recovered from Covid-19, sent a message from himself and the Duchess of Cornwall to Mr Johnson on Tuesday, also wishing him a 'speedy recovery', Clarence House said.
Buckingham Palace said the Queen's message was conveyed through Mr Johnson's office.
Weekly calls between Number 10 and the Queen will not take place while the Prime Minister is receiving treatment in intensive care, Downing Street has confirmed.
Foreign Secretary Dominic Raab, who is deputising for the PM, will not be asked to step in to brief her on Boris Johnson's behalf.
Mr Johnson would have been due to have a telephone audience with the 93-year-old Queen, who is staying at Windsor Castle with a reduced household for her safety, on Wednesday.
The Queen delivered a message of hope to the nation on Sunday evening, just over an hour before Downing Street announced Mr Johnson had been admitted to hospital.
She warned the country, in lockdown with thousands dead after contracting Covid-19, 'may have more still to endure'.
But she said if we 'remain united and resolute' in the face of the coronavirus outbreak 'we will overcome it', and echoed the words of Forces' sweetheart Dame Vera Lynn's Second World War song, when she said 'we will meet again'.
Earlier on Tuesday, the Queen praised the 'dedication to service' of nurses, midwives and other health workers during the coronavirus outbreak, in a message to mark World Health Day.
She thanked the healthcare profession for its 'selfless commitment and diligence as you undertake vitally important roles to protect and improve the health and well-being of people across the Commonwealth, and across the world'.
The Queen addressed the nation on Sunday night, in a historic speech amid the coronavirus outbreak, and was watched by at least 23.3million people in Britain last night and millions more around the world

The Queen has praised the 'dedication to service' of nurses, midwives and other health workers during the coronavirus pandemic in a message for World Health Day.
The monarch, who is currently residing at Windsor Castle with her husband Prince Philip, also thanked healthcare professionals for their 'selfless commitment'.
She also praised their 'diligence' in 'vitally important roles to protect and improve the health and well-being of people across the Commonwealth and across the world'.
The head of state also said that 'testing times' can bring out 'the best of the human spirit', adding that healthcare workers' dedication was 'an example to us all'.
Her words were released in a video montage on the Royal Family's Twitter account showing members of the monarchy meeting medical staff and health workers.
Boris Johnson is 'breathing without assistance' in intensive care and does not have pneumonia, Downing Street said categorically today.
Forced to issue a statement to quash rampant speculation, the PM's spokesman said he was 'stable overnight and remains in good spirits', having received 'standard oxygen treatment'.
Mr Johnson has also not needed a mechanical ventilator despite mounting concerns over his health.
The more positive news came after Michael Gove said the premier's plight is 'truly frightening' and ministers are 'praying' for his swift recovery. Foreign Secretary Dominic Raab has been 'deputised' to take charge while he is out of action..
But there are growing concerns about the effectiveness of the government machine while the incumbent of No10 is unable to lead the crisis response.
Mr Johnson was moved to ICU at St Thomas' Hospital in central London and given oxygen last night after his health deteriorated sharply over just two hours, leaving doctors fearing he will end up needing a ventilator.
But the 55-year-old's spokesman said today: 'The Prime Minister has been stable overnight and remains in good spirits.
'He is receiving standard oxygen treatment and breathing without any other assistance. He has not required mechanical ventilation or non-invasive respiratory support.'

Some users, however, dubbed the tribute a 'ridiculous idea' and took the opportunity to criticise the Prime Minister.

The Prime Minister's sharp downturn came 11 days after he first suffered coronavirus symptoms and went into isolation.
He looked increasingly unwell when seen in public and in 'selfie' videos posted on social media, and ministers were said to be shocked by his appearance at a Zoom conference on Sunday.

Downing Street sources confirmed Mr Johnson is not yet on a ventilator - but was moved to intensive care to be near one if needed.
Some medical experts are forecasting this course of action is now 'very likely'.
Two thirds of patients in intensive care with coronavirus are sedated and put on a ventilator within 24 hours of arriving as the illness attacks their lungs.
But last night one doctor told The Times Mr Johnson was conscious and had not been intubated - the process of putting a tube in the windpipe to aid breathing.
He was said to have required around four litres of oxygen rather than the 15 litres used by an average Covid-19 ICU patient.
Only two hours before his move to intensive care, No10 was insisting Mr Johnson was still spearheading the government's coronavirus response, despite de facto deputy Mr Raab chairing the morning crisis meeting.
Yet shortly after the Foreign Secretary left the Number 10 podium following the daily 5pm press briefing, Mr Johnson suffered breathing problems.
Sir Mark Sedwill, the cabinet secretary, held an emergency video conference with the cabinet to tell them the bad news, in a moment one minister described as 'truly shocking'.
No10 has been urged to be more 'transparent' about the premier's condition, amid claims a hospital bed was being prepared for him as early as last Thursday.
