The wife of former British prime minister Boris Johnson, Carrie Johnson, on Friday took to social media to announce that she is pregnant with the couple’s third child.

Posting on her Instagram, Boris Johnson's wife said: "New team member arriving in just a few weeks. I've felt pretty exhausted for much of the last eight months but we can't wait to meet this little one.

“Wilf is very excited about being a big brother again, and has been chattering about it non-stop. Don't think Romy has a clue what's coming... She soon will!”
