Boris Johnson's pregnant sister-in-law confirms she also has coronavirus

Boris Johnson's sister-in-law has said she has also tested positive for Covid-19. Gabriela Maia, who is married to Boris's financier half-brother, Max, said she is "still recovering from the virus with some respiratory difficulties".

The 30-year-old, who is pregnant, told the Daily Mail: "I am OK now and I just feel so lucky to be alive and I pray that my baby is safe.

"My heart just melts for the ones who haven't been so lucky. It's really, really sad."

It comes after Boris Johnson shared a video message on Twitter confirming he had contracted the virus.
