BORIS Johnson and Carrie Symonds are expecting their first baby together and have today announced their engagement.
The “very happy” couple revealed the news tonight with their child due early in the summer.
A court recently paved the way to finalise his divorce from estranged wife Marina Wheeler – which would leave him free to marry Carrie.
Carrie, 31, and hubby to be Boris tonight confirmed the news.
Writing on her private Instagram account, Carrie said: “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 know, we got engaged at the end of last year… and we’ve got a baby hatching early summer.”
Keen conservationist Symonds was steadfast by Boris’s side throughout his battle for PM and his election victory after first going public with their relationship during his leadership bid in June 2019.
They are thought to have been dating for roughly two years, and have been living in Downing Street with dog Dilyn since Boris became prime minister in July.
A No.10 source added: “Boris and Carrie are both delighted at this news.
“They have both known for a while but have kept it under wraps until the pregnancy progressed.
“It partly explains why he has been lying low recently – although he works flat out and that won’t change.
“Carrie is thrilled and she will also continue to work on her environmental projects.”
Carrie was the first unmarried partner of a sitting Prime Minister to live on Downing Street.
And the couple now have their five-year term in office to put down roots and plans.
