SNP MP Margaret Ferrier will face no further action from the Metropolitan Police after she travelled between London and Glasgow after testing positive for Covid-19.

Scotland Yard said in a statement yesterday that regulations under which the politician might have been prosecuted were not in effect when she travelled.

The SNP whip was withdrawn from Ms Ferrier after it emerged that she travelled from Glasgow to the House of Commons while awaiting the result of a test she took on September 26. 

She then made the return journey after being informed she had the virus.

The Rutherglen and Hamilton West MP’s test was taken before September 29, when new regulations came into effect that could have resulted in a £10,000 fine being levied against her.

The Met said that Police Scotland still had the option of taking action.

A spokesman for the SNP said: “Police Scotland and the parliamentary standards commissioner are still considering matters.

“It is important that due process is followed and we will not be offering further comment. Ms Ferrier remains suspended from the SNP.”
