The Secretary of State for Scotland, Alister Jack, is self-isolating after he developed coronavirus symptoms.
Mr Jack is said to be experiencing “mild” symptoms, including a cough and a temperature, but had not been tested for Covid-19.
He said in a statement: “In the past 24 hours, I have developed mild symptoms associated with coronavirus.
Mr Jack added: “In line with medical guidance, I am self-isolating and working from home.”
On Wednesday, Mr Jack – who is the MP for Dumfries and Galloway – was on the front bench in the House of Commons chamber with Prime Minister Boris Johnson.
