Boris Johnson has revealed that doctors were preparing to announce his death as he fought coronavirus.
The Prime Minister said he received 'litres and litres of oxygen' to help him fight the deadly virus.
He has now described how a 'death of Stalin'-style scenario was prepared in case he passed away.
Mr Johnson added that his time in hospital was a 'tough old moment' in an interview with the Sun on Sunday.
The Tory also admitted his doctors 'forced' him to go to hospital as he was reluctant to leave Downing Street.
He told the newspaper: "It was a tough old moment, I won’t deny it. They had a strategy to deal with a ‘death of Stalin’-type scenario.
"The doctors had all sorts of arrangements for what to do if things went badly wrong.
"It was hard to believe that in just a few days my health had deteriorated to this extent."
The Prime Minister added that at one point doctors were considering putting a tube down his throat.
He suggested it was at this moment they started to think about how to 'handle' his death 'professionally'.
Mr Johnson had a face mask and a 'little nose jobbie' providing him with oxygen in hospital.
The politician recalls that as he was rushed to intensive care he asked himself 'how am I going to get out of this?'
He felt frustrated and confused about his inability to recover from the disease.
Mr Johnson announced on March 27 that he had tested positive for coronavirus and was self-isolating in Downing Street.
At that time, he said he had suffered mild symptoms, including a fever and cough, but would continue to lead the Government.
The Prime Minister has now revealed he was feeling 'pretty wasted'.
He was admitted to St Thomas' Hospital, a short drive from Downing Street, on April 5 after his condition deteriorated.
He spent three nights in intensive care before returning to a ward.
After a week in hospital he was released on April 12 to continue his recovery at Chequers.
On Wednesday, just over two weeks after leaving hospital, Mr Johnson oversaw the birth of his son Wilfred Lawrie Nicholas Johnson.
He was with his fiancée Carrie Symonds as she gave birth to their boy, in a moment he has described as 'extraordinary'.
The couple named their child Nicholas after Dr Nick Price and Dr Nick Hart, who cared for Mr Johnson while he was recovering.
The 55-year-old was initially reluctant to go to hospital, however his doctors insisted as his symptoms became worse.
Despite being taken to intensive care, Mr Johnson refused to even consider the idea that the disease could kill him.
He said a 'terrible buoyancy' within him meant he felt he would be fine in the end.
