Labour has tabled a cross-party motion to try to stop a future prime minister pushing through a no-deal Brexit against the wishes of MPs. The party plans to force a vote on Wednesday which would give MPs control of the timetable on 25 June. Labour says if the motion passes, MPs will be able to introduce legislation on that day to avoid a no-deal scenario at the end of October. Some Tory leadership hopefuls have said they would leave the EU without a deal. For others, including Rory Stewart and Mark Harper, the prospect is unacceptable. However, neither man appears prepared to back the opposition motion. Mr Harper said his "instinct" was to oppose it while Mr Stewart - despite saying he was "wholly supportive" of the idea at his campaign launch in London - later tweeted. Leaving on a no-deal basis - without any agreement on the shape of the future relationship between the UK and EU - could lead to significant disruption. The EU has previously said border checks would have to be brought in, affecting things like exports and travel and creating uncertainty around the rights of UK citizens living in the EU and vice-versa. The government normally controls business in the Commons - but MPs have previously seized control to legislate in favour of extending the Brexit process. Labour's Brexit spokesman Sir Keir Starmer said MPs "cannot be bystanders" while the next prime minister "tries to crash the UK out of the European Union without a deal and without the consent of the British people". "That's why we are taking this latest measure to end the uncertainty and protect communities across the country," he said. "My challenge to MPs who disagree either with a no deal Brexit or proroguing Parliament is to back this motion and act in the national interest." Leadership candidates Dominic Raab and Esther McVey have both said they would consider shutting down Parliament early - proroguing - in order to drive through no deal. Three ToriesThe motion has cross-party backing, including from one Tory MP - Oliver Letwin - who is supporting Michael Gove in the leadership contest. It has been signed by Jeremy Corbyn, SNP Westminster leader Ian Blackford, Lib Dem leader Vince Cable, Plaid Cymru Westminster leader Liz Saville-Roberts and former Green Party leader Caroline Lucas. Due to the confidence and supply agreement with the Democratic Unionist Party, the Tories have a majority in Parliament of five. That means it would take only three Conservatives to vote with the Labour motion for it to pass - if all opposition party MPs back it. Former Tory Attorney General Dominic Grieve signalled his support, telling BBC Radio 4's World Tonight it was the "right course of action" and would "head off a major crisis". And former Conservative MP Nick Boles, who now sits as an independent, said he would be flying back specially from a foreign trip to back the motion. But International Trade Secretary Liam Fox told the BBC the move was "typical of the current Labour Party", saying: "Jeremy [Corbyn] wants to be a Remainer in the south and a Leaver in the north." "If Labour tomorrow wants to make no deal impossible, they are making revocation [of Article 50] and staying in the EU a possibility." Justice Minister Robert Buckland called it "parliamentary game-playing", asking: "What is the point of all this sound and fury?"
