Boris Johnston and wife Carrie welcome arrival of fourth child Poppy

Former prime minister Boris Johnson and his wife Carrie Johnson have welcomed a fourth baby to the family.

The former leader of the Conservative Party can be seen holding his daughter, Poppy Eliza Josephine Johnson, in an Instagram post shared on Saturday.

Mrs Johnson shared a carousel of photographs announcing the news, adding that their baby was born on May 21 and that they are “totally smitten”.

In the caption, Mrs Johnson wrote: “Welcome to the world Poppy Eliza Josephine Johnson born on 21st May.

“I can’t believe how pretty and tiny you are. Feel so incredibly lucky. We are all totally smitten. Not sure I’ve slept a minute since you were born as can’t stop looking at how completely lovely you are.”

The couple were married in May 2021 at Westminster Cathedral and share three children, Wilfred, Romy and Frank, with Poppy joining as the “final gang member”.

Mr and Mrs Johnson had their first child, Wilfred, in April 2020, in the early months of the Covid-19 crisis.

Mrs Johnson added: “Wilf, Romy and Frank are utterly delighted, particularly Romy who was desperate for a little sister. Bring on the matching dresses.

“A final gang member.

“Back from hospital now and time for cocktails and pizza with my tiny baby snoozing on my lap. Life doesn’t get any better.”

Johnson, 60, also shares four children with his ex-wife, lawyer Marina Wheeler, and a child, born in 2009, as a result of an affair with art consultant Helen Macintyre.

Succeeding from Theresa May, Johnson was prime minister from July 2019 until his resignation in September 2022.
