On the various comments on the rest of Europe, why we're extending restrictions whereas most of the rest are relaxing. Trying to avoid the whys and wherefores, and look at the data.
Here's current case data, on log plot so the wide differences can be seen on one graph. Just a few selected countries.

Denmark does more testing than anyone else, Germany far less than us.
Denmark I've picked out because, I think it's universally acknowledged, they have managed the epidemic better than almost any other Western country.
Trends are very clear; our cases are rising fast and exponentially in the UK. Most of the rest of Europe is falling, some precipitously. You can see why further relaxation is a big risk.
On vaccination, Europe is ~6 weeks behind us, but catching up slowly. Even if the delta variant causes the rise now seen here elsewhere, vaccination across Europe will catch up before it reaches our levels, I think (doubling time ~10 days in the UK).
Overall, most of Europe (including us - I mean geographical Europe) is going to come out of this almost together.
The UK will have a higher death toll per capital than most, but by no means all - I think Hungary is worst, and Italy the other large country slightly worse than us.
