Motion C - Customs Union
Put forward for a second time by the senior Tory Kenneth Clarke, this motion seeks for a Brexit deal to include, as a minimum, a commitment to negotiate a "permanent and comprehensive UK-wide customs union" with the EU.
This was the closest of the votes in the first round of indicative votes last week, and was just six short of a majority. Expect a monumental row within the Conservative Party if this passes the floor of the Commons.
Motion D - Common Market 2.0
Tabled by the Conservative Nick Boles, this motion proposes the UK negotiates membership of the European Free Trade Association (EFTA) and the European Economic Area (EEA). It allows continued participation in the single market and a "comprehensive customs arrangement" with the EU after Brexit - including a "UK say" on future EU trade deals - would remain in place until the agreement of a wider trade deal which guarantees frictionless movement of goods and an open border in Ireland.
Motion E - Confirmatory public vote
Drawn up by Labour MPs Peter Kyle and Phil Wilson, this measure if passed would require a public vote to ratify any Brexit deal,
This motion was tabled last week and received the highest number of votes, but was still rejected by 295 votes to 268. This means it would have to attract 27 more votes today in order to pass the Commons.
Motion G - parliamentary supremacy
SNP MP Joanna Cherry joins with Mr Grieve and MPs from other parties with this plan to seek an extension to the Brexit process, and if this is not possible then parliament will choose between either no-deal or revoking Article 50.
An inquiry would follow to assess the future relationship likely to be acceptable to Brussels and have majority support in the UK.
