• ‘We cannot change what we are’: Michel Barnier stares down Tory threats

The EU’s chief negotiator, Michel Barnier, has said Boris Johnson’s government will have to bear full responsibility for a no-deal Brexit, as more than three years of talks between the UK and Brussels appeared on the brink of collapse last night.

In what appeared to be the opening shots in a blame game as both sides sense failure, Barnier said he could not see how a deal could be done unless the British side came forward with revised proposals within days.
