His great mistake was in not finding a way to provide his own members with cover so that they could manage a clean Brexit. Instead he was forced to expel 26 and lost one as well in a debacle.
Boris Johnson has the right objective but he has got to manage better.
How would you define "clean" here?
I think you could define it as either Brexit with a land border built through Ireland with hard stop checkpoints staffed by men with guns. Or, a Brexit where Ireland is left with no border and North Ireland is left outside the UK.
