Boris Johnson's son named after doctors who 'saved' PM's life

British Prime Minister Boris Johnson and his fiancée Carrie Symonds have named their son Wilfred Lawrie Nicholas.

It's in honour of their grandfathers and the doctors who treated the leader as he battled COVID-19.

The choice of Nicholas was to honour Nick Price and Nick Hart, the two doctors who treated Johnson, Symonds wrote in an Instagram post.

"I couldn't be happier," she said, adding, "My heart is full."

Johnson, who had returned to work on Monday after receiving treatment at London's St Thomas' hospital, had thanked the doctors for "saving his life".
