It was tabled by veteran Conservative Europhile Ken Clarke, backed by Labour's Yvette Cooper, Helen Goodman and chair of the Commons Exiting the EU Committee Hilary Benn and Tory former ministers Sir Oliver Letwin and Sarah Newton.
Labour's plan
Labour has tabled a motion again proposing its plan for a close economic relationship with the EU.
The plan includes a comprehensive customs union with a UK say on future trade deals; close alignment with the single market; matching new EU rights and protections; participation in EU agencies and funding programmes; and agreement on future security arrangements, including access to the European Arrest Warrant.
Revoke Article 50
Under this plan, if the Government has not passed its Withdrawal Agreement, it would have to stage a vote on a no-deal Brexit two sitting days before the scheduled date of departure.
If MPs refuse to authorise no-deal, the Prime Minister would be required to halt Brexit by revoking Article 50.
The motion, tabled by the SNP's Joanna Cherry, has been signed by 38 MPs including Conservative former attorney general Dominic Grieve, Liberal Democrat leader Sir Vince Cable, Labour's Ben Bradshaw and all 11 members of The Independent Group.
Confirmatory public vote
This motion would require a public vote to confirm any Brexit deal passed by Parliament before its ratification.
It was drawn up by Labour MPs Peter Kyle and Phil Wilson and tabled by former foreign secretary Dame Margaret Beckett with the backing of scores of MPs across the House.
Contingent preferential arrangements
A group of Conservative MPs, including Marcus Fysh, Steve Baker and Priti Patel, have signed this motion.
It calls for the Government to seek to agree preferential trade arrangements with the EU, in case the UK is unable to implement a Withdrawal Agreement with the bloc.
