Boris Johnson has been pictured with his baby son Wilfred for the first time.
The image released by Downing Street shows the prime minister and his partner Carrie Symonds with Wilfred, who is now 11 weeks old.
The couple are seen speaking on a Zoom call with midwives, some of whom cared for Ms Symonds and Wilfred at University College Hospital in London.
Wilfred was born on 29 April, just over two weeks after the prime minister left hospital after being seriously ill with COVID-19.
Ms Symonds said they named their son Wilfred Lawrie Nicholas Johnson after the couple's grandfathers and the two doctors called Nick who "saved Boris' life".
Ms Symonds reportedly told the midwives on the Zoom call how "incredibly grateful" she was for the "most amazing care" she had received in hospital, and thanked them for "the brilliant work they do day in and day out".
Following Wilfred's birth, Ms Symonds said: "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."
Wilfred's birth weight was not disclosed. Downing Street declined to say whether the baby was born prematurely, and has not provided any other details about the birth.
A spokesperson said the PM will take a short period of paternity leave later this year.
Mr Johnson, 55, and 32-year-old Ms Symonds made history as the first unmarried couple to officially live together in Downing Street when they moved in last July.
The baby is Ms Symonds' first child, while Mr Johnson already has four grown-up children with his second wife Marina Wheeler; Lara, Milo, Cassie and Theodore.
The PM also has a daughter with art consultant Helen Macintyre.
Asked how many children he had during the general election in November, he told LBC: "I love my children very much but they are not standing at this election. I'm therefore not going to comment on them."
Wilfred is the third baby born to a serving prime minister in recent history.
Tony Blair's wife Cherie gave birth to son Leo in May 2000, three years after her husband's first election victory, and David Cameron and wife Samantha welcomed daughter Florence in 2010.
The last babies born to prime ministers before Leo and Florence arrived more than 150 years ago.
