NICOLA Sturgeon has called for Dominic Cummings to be fired for breaking lockdown rules.

The First Minister said "integrity of vital public health advice" is the most important thing.

She compared the Cummings case to the resignation of Catherine Calderwood as Scotland’s chief medical officer after she visited her second home twice earlier in the crisis.

Sturgeon tweeted: "I know it is tough to lose a trusted adviser at the height of crisis, but when it’s a choice of that or integrity of vital public health advice, the latter must come first. That’s the judgment I and, to her credit, Catherine Calderwood reached. PM and Cummings should do likewise."

Initially it was suggested Cummings drove 250 miles between London and Durham despite the guidelines on travelling, and while showing symptoms of coronavirus.

However fresh claims emerged in the Observer and Sunday Mirror that he made a second trip to Durham last month after having returned to work at Westminster.

Kirsty Blackman, the SNP's Westminster deputy leader, and Ian Blackford, the SNP group's Westminster leader, have both called on Cummings to resign.
