My guess on restrictions easing:
I am optimistic that schools will reopen a month from today as planned but can see some year groups going in on alternate days until Easter to help reduce virus spread. I would assume that colleges and universities will reopen on the same date, and would like to think so too as many students who study practical courses like myself have been unable to access facilities vital to their studies for weeks. I know the Welsh government have borne this in mind for their education reopening on the 22nd so hopefully Boris will do the same regarding higher education.
Outdoor leisure poses a lower transmission risk than education settings so I can see golf courses etc also opening on the 8th. 23rd March marks the anniversary of the first lockdown so would make sense to reopen non-essential retail, gyms and hairdressers from this date.
I can see household mixing and domestic travel being allowed again from Easter, followed by reopening of hospitality and leisure during the middle of April when kids are back at school. This leaves a few more weeks before I reckon the rule of six, masks and social distancing are quietly dropped at the end of May.
This leaves mass gatherings and travel restrictions as the most dominant issues. Despite the optimism many people have about going abroad this summer, I’m not so sure it will be a free for all with the constant risk of new variants. I think what will happen come June is that travel corridors will be reinstated to countries with low infection rates, while anyone wishing to fly must have a negative test beforehand. Same goes for mass gatherings; If we can contain the virus, I don’t see why stadiums, festivals and nightclubs should not be allowed to open from this summer if all attendees can get tested beforehand.
Eventually, I think we will end up in a New Zealand-like situation where domestic life will be able to largely carry on as normal, but more stringent checks on crossing borders are in place for years to come until the pandemic is over globally.
