Varian, in regard to your post @19:36 today, the bond of trust, as you state, will be lost only as long as the Cummings issue remains in the public limelight. By the middle of next week, other covid issues will be dominating the public agenda.
In a few weeks we shall then have the full economic reality of the Coronavirus lockdown with perhaps five to six million unemployed emerging from the crisis. In that situation, the Cummings issue will be long forgotten and it will be how this government handles that economic situation which will then determine whether any "bond of trust" exists or can be built between the electorate and Johnson's government.
As Harold Wison so rightly stated, "a week is a long time in politics".
