Conservative cabinet member Alister Jack has said he is self-isolating after experiencing symptoms of the coronavirus.

Mr Jack, the Scottish Secretary, said he has not been tested for COVID-19 and his symptoms are a mild temperature and a cough.

The Conservative MP for Dumfries and Galloway 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."

Mr Jack's self-isolation comes after the Prime Minister Boris Johnson and Health Secretary Matt Hancock announced they have tested positive for coronavirus.
