The prime minister and his wife Carrie Johnson have announced the birth of their second child, a baby girl.
In a statement, a spokeswoman for the couple said: “The prime minister and Mrs Johnson are delighted to announce the birth of a healthy baby girl at a London hospital earlier today.
“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.”
They have not revealed if the little girl has a name yet.
Up until recently, the PM, 57, refused to answer questions about how many children he had.
But in September, he told NBC he had six children, making the most recent arrival his seventh child.
He has four children with ex-wife Marina Wheeler, a child born in 2009 as a result of an affair with art consultant Helen Macintyre, and now two children with his current wife.
