Boris Johnson’s wife, Carrie, has given birth to a baby girl, they have announced, a second child for the couple and at least the seventh for the prime minister. “The prime minister and Mrs Johnson are delighted to announce the birth of a healthy baby girl at a London hospital earlier today,” a statement said. “Both mother and daughter are doing very well. The couple would like to thank the brilliant NHS maternity team for all their care and support.” The girl is a sister to their son, Wilfred, born in April 2020. The couple were married in a secret ceremony in May this year. Johnson had four children, all now in their 20s, with his second wife, the barrister Marina Wheeler. The couple’s divorce was finalised in 2020 after 25 years of marriage. He also has at least one other child from an extramarital relationship. Johnson has repeatedly refused to say precisely how many children he has fathered, although in an interview with NBC in September he affirmed he had six. The news comes amid a tumultuous week for Johnson as prime minister, who has had to launch an investigation into widespread reports of a lockdown-breaking party in Downing Street in December last year. When Wilfred was born, Johnson was still recovering from a bout of Covid that had resulted in him being admitted to intensive care. The prime minister was present throughout the birth, it is understood. A spokesperson for the couple said: “Both mother and daughter are doing very well. The couple would like to thank the brilliant NHS maternity team for all their care and support.” The pair were photographed walking into the hospital, reportedly at 7.40am. The Labour leader, Sir Keir Starmer, sent his congratulations to the couple on the arrival of their baby, and added: “Wishing your family health and happiness.”
