Boris Johnson and Carrie Symonds have announced the birth of a “healthy baby boy” at a London hospital on Wednesday.

“The prime minister and Ms Symonds are thrilled to announce the birth of a healthy baby boy at a London hospital earlier this morning. Both mother and baby are doing very well,” their spokesperson said.

“The PM and Ms Symonds would like to thank the fantastic NHS maternity team.”

Johnson returned to No.10 on Sunday evening take charge of the government’s response to the coronavirus crisis. He had been due to face new Labour leader Sir Keir Starmer at PMQs for the first time on Wednesday, but foreign secretary Dominic Raab will now stand in.

Johnson had been recuperating at Chequers following his discharge from hospital, where he had spent three nights in intensive care.

Symonds, who had also suffered from coronavirus symptoms, sent the the PM daily updates, including images of their unborn child, as he was treated at St Thomas’ Hospital in central London.

Johnson, 55, and Ms Symonds, 32, announced in March that they were expecting a baby in “early summer”, and that they had become engaged at the end of last year.

The PM has previously suggested he intends to take paternity leave, although it is not known if this remains the case given the coronavirus pandemic.

Following the birth of their child, Johnson will not be taking part in prime minister’s questions today.

Dominic Raab, the foreign secretary, will stand in for the PM and face Labour leader Keir Starmer in the Commons.
