According to him, he was at work when his wife phoned to say she had been sick and felt ill - and perhaps this was the virus. He went home - and then returned to work. There is a rule that if you have been in contact with a person who has symptoms , which may be indicative of the virus, you should leave your workplace and isolate for 14 days.
He then drove his wife and his child for 4 or 5 hours, in the enclosed environment of a car, knowing that both he and his wife probably had the virus or were about to get it. If he had intended a relative in Durham to care for the child, that person/persons were at risk of contracting the virus. My understanding is that, as it turned out, he and his wife and the child stayed in a property on his parents' land - so how did this solve the child care element? And do you really think that driving for half an hour to another town in order to test your eyesight is a credible reason for, yet again, breaking the rules?
Initially, Cummings said he had not visited Barnard Castle and it appears it was only because someone actually took his car number that he had to admit in the end that he did go there.
How can anyone justify this behaviour?
