We had a bit of warning, the government did nothing, they allowed major sporting events to carry on when the virus was ravaging mainland Europe.
Madrid had closed the schools, closed down mass gatherings, was in lockdown but 3000 residents were allowed to travel to a football match in Liverpool with no restrictions, and as they could not go to bars at home it is fair to think a few pubs were visited.
And how did those fans travel? Are there any direct flights from Madrid to Liverpool or did people travel on trains? Coaches? Fly then get a train or a coach? Drive, then a ferry then drive again?
I'm not blaming the fans, there were other factors, the Cheltenham festival and the VI nations went ahead. The PM attended events and visited people with covid who he shook hands with.
Meanwhile anyone entering the country was allowed to go where they wanted, symptoms were not even checked.
This country is made up of a series of islands with one province sharing an island with another nation.
When it comes to something like a contagious disease that is a huge advantage and it wasn't implemented.
Ireland closed schools and went into lockdown, NI didn't. NI should have been given the same restrictions as Ireland as should the rest of the UK.
Travel between areas should have been limited and people coming into the UK should have been, at the least, monitored, ideally isolated for 2 weeks.
BJ didn't cause covid but he reacted to it in a manner that helped it take hold, he has also allowed his friends and colleagues to get away with breaking restrictions, which means many people will think the restrictions don't really apply.
