The worst thing that could happen for the UK right now is Tory backbenchers to force - and Johnson to cave, which wouldn't be against his form we all know - an early lift on the measures.
For all the people screaming this lockdown isn't strict enough, combined with the vaccine roll out it seems to be working. It's crap, but it's working.
Shouldn't be lifted until mid-March at the very earliest, and even then it should just be schools in limited numbers (I'd leave that until after Easter personally) and maybe allow people to go and play golf or something, like they did last May in 2-balls only, just something easy to manage etc.
If they can just be clear that another 2-3 weeks of this come early March will be the answer to, come April, getting out of lockdown for good and starting to see the gradual easing back to some normality, I'm sure people could stomach it.
