Which indicative votes could MPs be casting their ballots on tonight?

MPs are expected to cast their ballots this evening for a series of Brexit options, as the House of Commons takes part in a second round of indicative votes.

Aimed at breaking the impasse over Brexit in Westminster, MPs will once again take control of the order paper after their first attempt failed to attract a majority for one route.

John Bercow, the Commons speaker, will decide which motions from those tabled will go forward to a vote around 6pm, and results are not expected to be announced until 10pm.

Here The Independent looks at the eight motions on the order paper.

Conservative backbenchers - led by John Baron - want Brexit to happen on 22 May with Theresa May's withdrawal agreement amended, enabling the UK to unilaterally to exit the Northern Irish backstop protocol.

This is something the EU have repeatedly made clear they will not countenance, and it is very unlikely to attract support from MPs.

Another motion put forward by the Conservative Brexiteer Mr Baron, which calls for a no-deal exit on 12 April if the prime minister continues to fail to gather sufficient MPs' support for her agreement.

Given the House of Commons has repeatedly expressed it wish to avoid a no-deal Brexit, expect this motion to be defeated resoundingly if it comes to a vote.

A similar motion tabled last week was supported by 160 MPs, but opposed by 400 MPs.

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.

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.

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.

Moved by Labour's Graham Jones and the Conservative MP Dominic Grieve, this motion would require a referendum on Brexit if it were necessary to prevent the UK crashing out of the EU without a deal.

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.

A motion tabled by Conservative MP George Eustice - who quit as agriculture minister to fight for Brexit - proposes rejoining the European Free Trade Association (Efta) at the "earliest opportunity", agree a short extension to the UK's membership of the EU to conclude accession to Efta and negotiate with the EU additional protocols relating to the Northern Ireland border and agri-food trade.

This received limited backing last week, with just 65 MPs voting in favour.
