SNP MP Margaret Ferrier is the latest high-profile figure to break coronavirus rules.
But what did she do and how does it compare to the political world's other rule-breakers?
Saturday 26 September
Ms Ferrier, MP for Rutherglen and Hamilton West, started experiencing "mild symptoms" of coronavirus in the afternoon and took a test. It is not clear where she was at the time.
Monday 28 September
Ms Ferrier said she was "feeling much better" so took a train to London.
That evening, she gave a four-minute speech in the House of Commons during a debate on coronavirus.
At some point she received a positive result from the test but it is not clear whether this was before or after her parliamentary address.
Tuesday 29 September
Ms Ferrier said she boarded a train in the morning without seeking advice but began isolating when she arrived in Glasgow.
Wednesday 30 September
Two days after being notified about the positive test, she informed the SNP. Party officials have said they did not know at this stage that she had taken the test before travelling to London.
Commons Speaker Sir Lindsay Hoyle was also told and contact tracing began.
Thursday 1 October
Ms Ferrier reported herself to Police Scotland and released a statement saying she was "very sorry for my mistake" and admitting she should have isolated while awaiting her test result.
SNP Westminster leader Ian Blackford suspended the whip from Ms Ferrier and party officials said they became aware she had taken a test before departing for parliament and had travelled back to Scotland knowing it had come back positive.
Scotland's First Minister Nicola Sturgeon condemned her actions as "utterly indefensible", but, despite growing calls for Ms Ferrier to go, Ms Sturgeon did not announce her sacking.

The prime minister's closest aide drove to Durham in March, more than 260 miles from where he lives in London – after the instruction was issued telling people they must stay at home.
He was recovering from coronavirus symptoms at the time but, despite calls for him to resign, he said he had behaved "reasonably" and had no regrets.
