Donald Trump’s coronavirus diagnosis has “thrown a wrench” in the current president’s re-election campaign, an expert has said.

Julie Norman, a lecturer at University College London’s Centre on US politics, said Mr Trump’s diagnosis may not have surprised many people following his campaign.

She told the PA news agency: “I think for anyone who has been watching Trump and following his actions during the course of the pandemic – the fact that he has been hosting and going to large gatherings, he has not been wearing a mask – we know those things certainly increase the risk for someone to contract Covid.

“So the fact that he did, I guess, should not be too surprising, but the news certainly was a surprise for most people I think this morning.”

The US president’s diagnosis comes only weeks before US election day on November 3 and in a “very tumultuous week” for the race, Dr Norman said.

As Mr Trump will need to self isolate for the next 10 days, all campaign events will have to be cancelled or held remotely for what effectively amounts to a third of the remaining time before election day.

“This really does throw a wrench in everything, it’s unclear how the future of the campaign will look for Trump,” she added.

Scotland has recorded four new coronavirus deaths in the past 24 hours, Nicola Sturgeon has announced, and the number of cases has now passed 30,000.

First Minister Nicola Sturgeon has again called for MP SNP Margaret Ferrier to resign after she travelled from London to Scotland when knowing she had tested positive for coronavirus.

Ms Sturgeon made the announcement during her daily Covid-19 briefing to the nation during which she said how “angry” she was on behalf of the country in response to Ms Ferrier’s actions.

She said she has spoken with the MP for Hamilton in person making it “crystal clear” that she thinks Ms Ferrier should resign.
