Dumfries & Galloway MP and Scottish Secretary Alister Jack has developed mild symptoms of coronavirus in the past 24 hours and is self-isolating, he has said.
The Conservative MP said he has not been tested for the virus and his symptoms are a mild temperature and a cough.
He said: "In the past 24 hours, I have developed mild symptoms associated with coronavirus.
"In line with medical guidance, I am self-isolating and working from home."
One of their top coronavirus advisers has also been forced into self-isolation after also experiencing "mild symptoms", but like the PM and health secretary, Chief Medical Officer Chris Whitty will continue to work from home.
Mr Johnson, who is suffering with a "temperature and persistent cough", says thanks to the "wizardry of modern technology" he can continue to manage the response by communicating via video.
Mr Gove said the diagnoses of his colleagues shows that the “virus does not discriminate”, adding: “We are all at risk.”
