"Once Sovereignty guaranteed with no EU control" - I would like to know where we lost Sovereignty in the first place. Is it not clear from the proroguing of parliament last year that we clearly still have Sovereignty.Well if this Cummings issue shows EU anything its that Boris isn't going to be pushed around/intimidated! Even if he's wrong.
Sovereignty over EU Trade deal.
Once Sovereignty guaranteed with no EU control, can evolve trade going forward if it has to be that way based on EU/UK political dogma.
And the Cummings situation is not a good one for Boris, his ratings have fallen sharply and it shows he will bow down to others and be pushed around by an adviser. Beaten into defending someone who the police have said broke lockdown rules. He's a coward.
