Boris and Carrie Johnson have announced the name of their daughter, Romy Iris Charlotte Johnson. Carrie Johnson, posting on Instagram, said Romy was picked after her aunt Rosemary, Iris after the Greek word for rainbow, and Charlotte after the prime minister’s late mother. She has previously described her daughter as a “rainbow baby”: a term to describe a child born after a miscarriage. The 33-year-old has spoken of having a miscarriage earlier in the year. The prime minister revealed the first name of his seventh – or possibly eighth – child to reporters while on a visit to a Covid vaccination centre in Kent. The couple announced Romy’s birth on 9 December. She is the second child of the prime minister with his third wife, following the birth of their son, Wilfred, in April 2020. Johnson, 57, has four children with his former wife, the barrister Marina Wheeler, and one – Stephanie – with the art consultant Helen Macintyre, with whom he had an affair while he was mayor of London in 2009. The prime minister had previously denied being ​​Stephanie’s father but in 2013 the court of appeal ruled it was in the public interest for the details of his extramarital affair to be known. In an interview with NBC in September last year, Johnson said he had six children. But during the 2013 court ruling, the three judges suggested there may be a second child from an extramarital affair, making eight children in total. No details are known about the alleged second child. The prime minister did not take an extended period of leave after Romy’s birth as he battles a string of political scandals as well as the spread of the Omicron Covid variant.
