The Hamilton MP who tonight admitted breaching Covid-19 travel rules previously called on the Prime Minister’s chief advisor to lose his job after it was revealed he drove 260 miles from his home to Durham during lockdown.
Ms Ferrier admitted to travelling south by train while waiting for the results of a coronavirus test, and travelling back north by train the next day when she received the positive result.
Earlier in the year, while talking about Mr Cummings, she said: ".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."
Back in May, Margaret Ferrier said Dominic Cummings should stand down after it was revealed he had travelled with his wife and son to Durham, despite feeling unwell with coronavirus symptoms.
Mr Cummings was later diagnosed with the illness. He claimed he needed to make the trip so that his young son was nearer family members who could help with childcare.
At the time, Ms Ferrier said: “Dominic Cummings’ actions have undermined the sacrifices that we have all been making in lockdown to protect each other from coronavirus. His position is untenable and he must be removed from his post now.
“The fact that Boris Johnson and senior Tories have backed Dominic Cummings, in the face of widespread and understandable public anger, demonstrates a total failure of leadership at a time of national crisis.
“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.
“Anyone who needs help during periods of self-isolation should make use of the support offered through local authorities, which is open to anyone who needs it.”
Ms Ferrier is now facing calls that she should stand down.
