"asked people not to go to a and unless life threatening "
Sounds like usual guideline to visit A&E... but I suppose Should people with bad allergic reactions, broken bones & deep cuts just try to sort them at home--not life threatening after all, or maybe just not yet.
Nobody says this but Nightingale were just palliative centres for the covid patients, weren't they? At best keep the patients comfortable until they die, knowing they couldn't be helped due to lack of right staff.
