Not sure if it was mentioned in another thread but I saw tonight that it looks like the Government plans are that we will see this lockdown lifted at the beginning of April.

This thread of tweets seems to suggest that cities will likely only go back into Tier's 3 and 4 though so we'll still be in a lockdown of sorts until May regardless of the vaccine rollout due to the shear number of cases at present. I guess any hope of things opening in February or March were a bit of a long shot with the new variant.
All seems so endless. Easter is 12 weeks or 51 working days away. I've never wished my life away so much and really hope we get an early Spring.
