Brexit news: EU leaders vow to block any trade deal if Boris Johnson breaches withdrawal agreement as Ireland accuses PM of ‘unprecedented provocation’

European parliament leaders have vowed to block any future UK-EU trade deal if Boris Johnson goes ahead with a bill which would violate the Brexit withdrawal agreement, after the bloc’s chief negotiator Michel Barnier said it was increasing its planning for a no-deal scenario.

The prime minister sought to fend off a looming revolt, reportedly telling some 250 Tory MPs that his planned breach was “necessary to stop a foreign power from breaking up our country” but that there was “no time for questions”, after Tory rebels tabled an amendment that would give parliament a veto on his Internal Market Bill.

It comes as Ireland’s Europe minister said the move to renege on last year’s deal was a “unilateral provocative act” that was “uniquely unprecedented” in history.
