No going back on promises made in EU-UK Brexit agreement, warns Barnier

There must be "no going back" on the Brexit agreement struck between the EU and UK last week on citizens' rights, the status of the Irish border and Britain's £39bn divorce bill, Michel Barnier has said.
The EU's chief negotiator was speaking as MEPs voiced concern over the UK's Brexit Secretary David Davis's suggestion that the joint report agreed by Prime Minister Theresa May and European Commission president Jean-Claude Juncker on Friday was "a statement of intent" rather than a legally binding document.
