prime minister, genuinely don't understand these differences. i wish i could pretend mr speaker that everything was going to be rosy in the midlands or indeed in london, mr speaker, where alas we are also seeing infections rise and that's why we need a concerted national effort. we need to follow the guidance. we need hands, face, space, get a test if you have symptoms, and obey the rule of six, mr speaker. and i think it quite extraordinary that the right honourable gentleman has just said that he personally supports the rule of six while allowing his entire party to abstain! next week, this house will vote on whether to approve the 10pm rule. the prime minister knows that there are deeply held views across the country in different ways on this. one question is now screaming out. is there a scientific basis for the 10pm rule? the public deserve to know. parliament deserves to know. if there is, why doesn't the government do itself a favour and publish it?
