BORIS Johnson has sent his best wishes to the Queen as she continues to rest after her overnight stay in hospital.
Downing Street said the PM had passed on a message to the monarch after news broke that she was taken in for an examination.
A No 10 spokesman said: “The Prime Minister’s best wishes have been passed on to Her Majesty.”
The spokesman wouldn’t say whether Boris had had his weekly audience at Buckingham Palace.
The Queen is said to be back at her desk already.
Royal doctors sent the 95-year-old sovereign to be seen by specialists in London on Wednesday afternoon.
Her Majesty was discharged — with Buckingham Palace saying she was in “good spirits” after “preliminary investigations” during her visit to hospital.
It was believed her medical team acted out of caution to have her admitted to King Edward VII hospital in Marylebone on Wednesday.
And the overnight stay — her first in a hospital for eight years — was for practical reasons.
Yesterday afternoon Her Maj, 95, was understood to be back at her desk at Windsor Castle.
A source quoted in the Daily Mail said: “Quite understandably, a cautious approach is being taken by the medical team.
“Her Majesty was back at her desk this afternoon and undertaking light duties.”
She was said to be reading her official government red boxes and is expected to recuperate for the rest of the week.
The famous boxes – which include policy papers, Cabinet documents, Foreign Office telegrams and a daily summary of events in Parliament – are sent to the monarch by her private secretaries wherever she is every day of the year.
The Palace said last night: “Following medical advice to rest for a few days, the Queen attended hospital on Wednesday afternoon for some preliminary investigations, returning to Windsor Castle at lunchtime today (Thursday) and remains in good spirits.”
Fifth major hospital trip in 40 years
It was believed the Queen stayed the night in hospital as it was getting too late to take her on a 26-mile trip home.
She was not thought to have had an overnight hospital stay since March 2013 when she was treated for a stomach bug at the same hospital.

And it was believed to be just her fifth major hospital trip in 40 years.
On Wednesday Her Majesty cancelled a two-day trip to Northern Ireland on doctors’ advice.
Aides hope she will be at Glasgow’s COP26 climate change summit with world leaders on November 1.
But experts have warned the Palace must now be “careful” not to over exert her.
Royal biographer Hugo Vickers told Good Morning Britain: “If you look at the programme she’s done it would have exhausted almost any of us in the last few days.
“Given that next year she’s got a very big year – the Platinum Jubilee to mark 70 years on the thrown – they (the Palace) do need to be careful I think so let’s hope she is getting some rest.”
The Queen will celebrate 70 years on the British throne in 2022 – the first time any British monarch has reached the historic milestone.
In the meantime she has had 14 engagements over the past three weeks — often with a walking stick.
She used it at Westminster Abbey and Cardiff last week but discarded it at Tuesday’s Global Investment Summit at Windsor Castle.
Mr Vickers said most of the Queen’s programmes are “arranged for her”.
And because her Maj doesn’t want to disappoint, she finds it “difficult to say to say no to things”.
But the expert added: “She can of course say no and occasionally she does but I do think sometimes they really do need to consider how to make it as easy as possible get maximum exposure of the queen with minimum effort to her to not tire her too much.”
