British Prime Minister Boris Johnson's fiancee, Carrie Symonds, has given birth to a "healthy baby boy" in a London hospital, Downing Street said on Wednesday, April 29.

"Both mother and baby are doing very well," the spokesman said in a surprise announcement, as Symonds was not thought to be due until later in the year.

Johnson returned to work on Monday, a month after testing positive for coronavirus, which he said had threatened his life. Symonds also had symptoms of Covid-19 but recovered swiftly.

Johnson, who refuses to say how many children he has in total, was previously married to Marina Wheeler, and they had four children together. They announced in September 2018 that they had separated and they divorced earlier this year.
