The advice is fucking mental. You can buy emergency DIY but not paint and brushes. No social gatherings unless on a bridge to applaud the NHS. You can fly into the country and step straight onto public transport. The whole thing is just a shit show because the guy in charge don't want to set defined boundaries.
Seriously if Corbyn was in charge of this he would be crucified but the population in England are saluting their fuckwit leader.
