British MPs are voting on four Brexit options, in the second round of indicative votes that could find a way out of the country's political deadlock. They have 30 minutes to cast their ballots.
There are four options, and MPs can vote on as many as they like:
Motion C, Customs Union -- This motion calls on the government to ensure that the Brexit plan includes a permanent and comprehensive UK-wide customs union with the EU.
Motion D, Common Market 2.0 -- This proposal wants the Political Declaration -- which covers the future relationship between the UK and the EU -- to be renegotiated so that the UK joins the European Free Trade Association, through which it retains its membership of the European Economic Area, or Single Market. The UK would also seek to negotiate a "comprehensive customs arrangement" with the EU.
Motion E, Confirmatory public vote -- Parliament would not be allowed to ratify any Brexit deal until it has been confirmed by a referendum.
Motion G, Parliamentary Supremacy -- This motion has a series of actions. If the no withdrawal agreement has been agreed by noon on April 10, the UK must seek a delay to Brexit from the bloc. If the EU does not agree to a further extension, then government must allow MPs to choose between leaving without a deal and revoking Article 50, which would scrap the Brexit process altogether.
