EAST Renfrewshire’s MP has added her voice to calls for controversial politician Margaret Ferrier to quit the House of Commons. 

Kirsten Oswald has branded Ms Ferrier’s decision to breach rules by travelling on public transport after receiving a positive coronavirus test result as “wholly unacceptable.”

The Rutherglen and Hamilton West MP, who has had the SNP whip withdrawn over her conduct, is refusing to resign from her £80,000 post.

In a message on her social media page, Ms Oswald, also of the SNP, said: “What Margaret did is absolutely and wholly unacceptable – and indeed inexplicable.

“Her position is not tenable and she should do the right thing and step down. It gives me no pleasure to say that, but that is clearly the reality.”

Ms Ferrier developed coronavirus symptoms and took a test on Saturday, September 26.

She breached rules by travelling to London the following Monday and taking a train back to Scotland on the Tuesday after receiving a positive result.
