'On Saturday, despite feeling ill enough to take a test, she travelled 400 miles to London by train on Monday – a journey lasting five hours and 40 minutes – to attend parliament, where she made a brief speech in the evening during a debate on coronavirus.
That evening she was also told she had tested positive for the virus. It is unclear whether she was told that before or after she spoke in parliament about the replacement of the furlough scheme.
The following morning, Tuesday, she travelled by train to Scotland without seeking advice but knowing she had the virus. She has been self-isolating at home since then. Commons authorities said she informed the SNP whips of the result on Wednesday afternoon.'
