Carrie Johnson has announced she is pregnant again 15 months after giving birth to her first child.

The wife of Boris Johnson published a post on Instagram stating she was expecting their second baby after suffering a miscarriage earlier this year.

Mrs Johnson, who was appointed head of communications for animal conservation group the Aspinall Foundation in 2021, has had a tumultuous few years since the couple confirmed their romance.

Her association with Mr Johnson dates back several years having worked on his successful bid to be re-elected Mayor of London in 2012.

But the couple did not start dating until 2018 after he announced he had separated from his second wife, Marina Wheeler, who is the mother of four of his children.

Mr Johnson was later elected Prime Minister in 2019 and the pair moved in to Downing Street together, making them the first unmarried couple to move into the historic home.

But two months after Mr Johnson took office, allegations about his relationship with American entrepreneur Jennifer Arcuri swirled in the press.

He has denied any impropriety in relation to the claims about Ms Arcuri.

In February 2020, the PM’s spokesperson announced Mr Johnson and Mrs Johnson, who was then known by her maiden name Carrie Symonds, were engaged and expecting their first child.

Just over three weeks later, Mr Johnson announced a nationwide lockdown due to the coronavirus outbreak in the UK and confirmed he had tested positive for the disease on March 27.

It was confirmed Mrs Johnson also self-isolated at the time but it is not known if she tested positive.

The PM was admitted to hospital on April 5 and was moved to intensive care a day later.

He was discharged on April 12 and the couple’s son, Wilfred Lawrie Nicholas Johnson, was born on April 29.

Later in 2020, she made her first joint television appearance with Mr Johnson to thank NHS workers for treating him in hospital and delivering their baby.

She also clashed with Mr Johnson’s former top aide Dominic Cummings at the tail end of last year, who alleged that she had distracted him from the pandemic by “going crackers” over “trivial” stories about them in the press.

Mr Cummings also recently claimed in a BBC interview there was a “big argument” after Mrs Johnson, a former Tory head of communications, was looking to appoint and fire people “in ways that I thought were unethical and unprofessional”.

No 10 said in response that political appointments are “entirely made by the Prime Minister”.

Mr and Mrs Johnson held a low-key wedding ceremony in May of this year at Westminster Cathedral.

Recently, the pair were photographed together at Wembley Stadium in north London at the Euro 2020 final between Italy and England.

It is thought to be the latest image of the pair in public together.

Mrs Johnson is the daughter of Matthew Symonds, a co-founder of The Independent, and Josephine Mcaffee, who was one of the paper’s lawyers.

She graduated from the University of Warwick with a bachelors degree in theatre studies and history of art in 2009 and began her career in politics that same year.

She joined the Conservatives first as a press adviser, then head of broadcast at Conservative Campaign Headquarters ahead of the 2015 general election.

She became the party’s head of communications in 2018 but left the role later that year.

Prior to political PR, Mrs Johnson had several jobs in the world of commercial communications and marketing.
