Boris Johnson to marry pregnant girlfriend Carrie Symonds

Boris Johnson has announced he and his partner Carrie Symonds, 31, are engaged and she is expecting a baby.

The 55-year-old Prime Minister said the couple are expecting a baby in the early summer.

The announcement means Mr Johnson will become the first Prime Minister to marry in office for 250 years.

It comes 11 days after he reached an agreement with his estranged wife Marina Wheeler, with whom he had four children.

A spokesperson for the couple 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."

Mr Johnson and Miss Symonds made history as the first unmarried couple to officially live together in Downing Street when they moved in last year.

Ms Symonds, a conservationist and former Conservative Party communications chief, first found herself making headlines when she was romantically linked to Mr Johnson earlier in 2019.

But her association with Mr Johnson dates back to when she worked on his successful re-election bid at City Hall in 2012.

In 2009, during his time as mayor, he fathered a child with art consultant Helen Macintyre.

Ms Symonds will be his third wife after Allegra Mostyn-Owen and Ms Wheeler.

An early summer birth would suggest the new arrival was conceived during the Autumn, around the time that the October 31 Brexit deadline was extended.

The couple's announcement comes on February 29, leap day, where women traditionally take to proposing to their partner.
