BORIS Johnson’s wife Carrie has given birth to her second child with the Prime Minister after a tumultuous 24 hours for Downing Street.

The Johnsons announced the birth of a “healthy baby girl” at a London hospital earlier on Thursday.

“Both mother and daughter are doing very well. The couple would like to thank the brilliant NHS maternity team for all their care and support,” a spokeswoman for the couple said.

The baby girl is reportedly the Prime Minister's seventh child.
