Throughout the world governments are unlocking their nation's economies. If Britain is not in step with that development then British businesses will sustain long term damage
Other governments are unlocking their nations' economies because their infection and death rates have come down to very low figures, or none at all. We are still recording over 1,000 new infections per day and 200+ deaths. More deaths per day than we had when we originally locked down after a fashion
If this means that in a few week's time we are into a second wave then we will, I assume, have to lock down again and any economic gains made in those few weeks will be wiped out. the whole exercise will have been pointless and engendered more deaths into the bargain.
