Britain’s Boris Johnson and his fiancee Carrie Symonds have named their newborn son after the two doctors who treated the prime minister for Covid-19 last month. Ms Symonds announced on her Instagram account that their son would be named Wilfred Lawrie Nicholas Johnson. She said the child was named after Mr Johnson’s grandfather Wilfred and her grandfather Lawrie. The middle name Nicholas is a tribute to Dr Nick Price and Dr Nick Hart, who saved Mr Johnson’s life when he was in intensive care last month after contracting the coronavirus. Ms Symonds praised the maternity team at University College Hospital in London, saying: "Thank you so, so much to the incredible NHS maternity team at UCLH that looked after us so well. "I couldn't be happier. My heart is full." Downing Street has said Mr Johnson will take paternity leave later this year. "We are honoured and humbled to have been recognised in this way," said Dr Price, director of infection at Guy's and St Thomas' hospital, and Dr Hart, director of respiratory and critical care. "We wish the new family every health and happiness." Mr Johnson, 55, was discharged from intensive care at St Thomas's Hospital in Central London on April 12 after testing positive for the virus in March. He spent the first 10 days of his illness isolating in Downing Street but after his symptoms worsened, he was rushed to the hospital on April 5. Mr Johnson spent a week in hospital and was admitted to the intensive care unit, where he was given oxygen to aid breathing but not a ventilator. After being discharged, he spent two weeks recovering at Chequers, the prime minister’s country residence. He returned to work on Monday but did not attend Prime Minister’s question in Parliament on Wednesday due to the birth of his son. Dominic Raab, the Foreign Secretary who was stand-in leader while Mr Johnson was recovering, attended instead. Britain has 178,689 known cases of the coronavirus and 27,510 people have died from it there, the latest data from Johns Hopkins University shows.
