UK’s PM Boris Johnson and his partner Carrie Symonds have named their baby boy Wilfred Lawrie Nicholas Johnson.

The names are a tribute to their grandfathers and two doctors who treated Boris Johnson while he was in hospital with coronavirus, Carrie Symonds wrote in an Instagram post.

Carrie Symonds also thanked staff at University College London Hospital, saying: “I couldn’t be happier. My heart is full.”

She posted a picture of herself with the baby, who was born on April 29.

The birth came just weeks after Boris Johnson was discharged from intensive care at another London hospital following treatment for coronavirus.

Carrie Symonds wrote on May 2 that their son shares his first name with Boris Johnson’s grandfather, and the first of his middle names, Lawrie, with her own.

Dr. Nick Price and Prof. Nick Hart offered their “warm congratulations” to the prime minister and Carrie Symonds.

They said in a statement: “We are honored and humbled to have been recognized in this way, and we give our thanks to the incredible team of professionals who we work with at Guy’s and St Thomas’ and who ensure every patient receives the best care.

“We wish the new family every health and happiness.”

Boris Johnson’s newborn is only the third baby born to a serving UK prime minister in living memory.
