Boris Johnson and his girlfriend Carrie Symonds are expecting their first child and are engaged to be married.
The couple have lived in Downing Street since Mr Johnson became prime minister in last July.
In a statement they said: “The prime minister and Miss Symonds are very pleased to announce their engagement and that they are expecting a baby in the early summer.”
Ms Symonds, 31, posted on Instagram:
“I wouldn’t normally post this kind of thing on here, but I wanted my friends to find out from me.
“Many of you already know but for my friends that still don’t, we got engaged at the end of last year… and we’ve got a baby hatching early summer.
“Feel incredibly blessed”.
This will be Mr Johnson’s third marriage.
He and former wife Marina Wheeler – married for 25 years – agreed a financial settlement in court last month.
They have four children.
Mr Johnson has also fathered another child.
