AN SNP MP has admitted breaking lockdown rules by travelling back and forth between Scotland and London by train while positive for coronavirus.

The Rutherglen MP, who previously called for Dominic Cummings to resign over his Barnard Castle trip, has issued an apology for her actions on social media. 

She said she had no excuse for her behaviour, and has now reported herself to the police.

"On Saturday afternoon, after experiencing mild symptoms, I requested a Covid-19 test which I took that day. Feeling much better, I then travelled to London by train on Monday to attend Parliament as planned. This was wrong, and I am very sorry for my mistake.

"On Monday evening I received a positive test result for Covid-19. I travelled home by train on Tuesday morning without seeking advice. This was also wrong and I am sorry. I have been self-isolating at home ever since.

"I have used Test and Protect and I have notified the House of Commons authorities who have spoken with Public Health England.

"I have also notified the police of my actions. 
"Despite feeling well, I should have self-isolated while waiting for my test result, and I deeply regret my actions.

"I take full responsibility and I would urge everyone not to make the same mistakes that I have, and do all they can to help limit the spread of Covid-19." 

When Boris Johnson's special adviser Dominic Cummings broke the lockdown rules at the start of the pandemic, Ms Ferrier called for him to resign from his job.

She said the aide had "undermined the sacrifices that we have all been making in lockdown to protect each other from coronavirus."

She said his position was "untenable and he must be removed from his post“ and added: "The public health advice is crystal clear. For the safety of others, anyone with coronavirus symptoms must self-isolate, in line with government guidance. They should not leave the house for any reason."
