I suppose there are three categories of people - those who do the right thing whatever the guidance or the law, those who do what they are told to do, only so long as they are told they must do it, and those who go there own way regardless of any effect on other people.

You fall in the first category, as any responsible person must, and the last lot I would say are beneath contempt.   But there are an awful lot who fall into that middle category, and they are the ones this policy will affect.

And that's why I think it is premature and irresponsible.

I would never regard anything Boris Johnson says as a reliable guide to anything.
