Labour leader Sir Keir Starmer is self-isolating after coming into contact with a positive case.
The 58-year-old politician will continue working but from home after a member of his private office staff caught the bug.
A spokesperson for the MP added: "Keir is well and not showing any symptoms. He will now be working from home.”
Prime Minister Boris Johnson and Foreign Secretary Dominic Raab both found themselves in a similar situation last month.
Both members of the UK Government came into contact with positive cases but remained symptom free.
Meanwhile, the Scottish Government announced 22 new Covid-19 deaths on Saturday.
A further 777 cases were discovered overnight while 945 people are currently being treated in hospital.
The total number of confirmed Covid-19 cases in Scotland now sits at 99,463.
