Boris Johnson and his wife Carrie have named their daughter Romy Iris Charlotte Johnson.
She said the name comes from her aunt Rosemary, Iris – for the Greek word for rainbow, and Charlotte after Mr Johnson’s late mother “whom we miss so much”.
Following the birth on 9 December, a spokeswoman said: “The prime minister and Mrs Johnson are delighted to announce the birth of a healthy baby girl at a London hospital earlier today.
“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 couple also have a son, Wilfred Lawrie Nicholas Johnson, who was born in April 2020 – just weeks after the prime minister was in intensive care with COVID-19.
Mrs Johnson, 33, announced she was pregnant with their second child in July 2021.
She also said she’d had a miscarriage earlier this year and felt “incredibly blessed” to be pregnant again – but added that she “felt like a bag of nerves”.
The couple got married in a small ceremony at Westminster Cathedral in May this year.
