UK politics news – live: Barnier accuses Boris Johnson of backtracking on Brexit commitments as ministers face questions over ‘world-beating’ test and trace system

Boris Johnson is facing new questions over the test and trace system he had promised would be “world-beating” – after leaked comments from a senior NHS official revealed it would initially be “clunky” and is not expected to be “world-class” until September or October.

It comes as the EU’s chief trade negotiator Michael Barnier accused Mr Johnson of “backtracking” on commitments he made during the Brexit process and cast doubt on the future of trade deal talks.

Mr Barnier warned that there had been “no significant progress” on any key points in negotiations since they began, adding: “I don’t think we can go on like this forever.”
