Not the case. Most, not all and not SD or masks as they have said those will be reviewed.
If cases rise in Autumn after all the mixing, things will be restricted again.
Do people really think that most people, especially the young who have very little to fear from the virus, will really continue to not hug their friends, start new relationships etc? That it's not absolutely ridiculous and cruel for the very elderly to spend their last months and years isolated without human touch and hugging their families?
People have been prepared to sacrifice an awful lot over the past year but there's a limit as to how long they'll continue doing it for. You do realise social distancing is so much more than keeping 2m apart in the Sainsbury's queue? It's the death of the hospitality industry, it's telling people that they can't hug their families and friends, start new relationships. Just live a normal bloody life.
Boris and his cronies will listen to whoever is shouting the loudest- let's not pretend for one second that this government ever wanted to trash the economy so I really think that will start becoming the main priority for them- pubs and restaurants couldn't sustain more restrictions in the autumn. Especially when the government can point to the vaccination programme etc, and especially when the more this goes on, the louder voices are likely to be from those opposing restrictions. The balance will have to flip and those who want to shut themselves away and never hug a friend again, well crack on, but don't expect that everyone else will continue existing living like it.
