The Brexit train has trundled on today, with reaction across Europe to the decision by Theresa May to return to Brussels and seek "alternative arrangements" to the Irish backstop.

In the Commons at Prime Minister's Questions, Jeremy Corbyn and the prime minister battled over what was next, as the Labour leader sought further detail on what would change and where Mrs May was willing to compromise.

Following PMQs, the two party leaders met for talks on what was next for Brexit. Labour described the talks as "serious and engaged", suggesting the prime minister was "interested in exploring details" around a customs union.

Politicians in Ireland criticised the backstop rejection, with Deputy Prime Minister Simon Coveney urging the prime minister to seek consensus before negotiations "ran out of road" and others accusing the prime minister of acting in bad faith.

In the European Parliament, European Commission President Jean-Claude Juncker and many MEPs were also critical - suggesting the withdrawal agreement would not be open for renegotiation and calling for a clearer direction of desire travel from Westminster.

And the EU's chief negotiator Michel Barnier says the Irish backstop is "part and parcel" of the UK's Brexit deal and will not be renegotiated.
