I cannot see the reason a quarantine for travellers is being brought in now. Surely this should have been done, as in other countries, when “lockdown” was first implemented. Are we closing the stable door after the horse has bolted?
It's generally agreed that this is an ill-thought-out to-late exercise, but the government is wary of u-turning yet again, so it will get lip service for a few weeks and then miraculously found not to be needed.
