The parliamentary vote on Theresa May's Brexit deal is finally set to take place on Jan. 15, yet with 115 Conservative MPs indicating they won't back the prime minister's plan, she faces an uphill battle to get it through the House of Commons.

So what happens if the deal is voted down? Government ministers are jostling for position as they make the case for their preferred solutions to the Brexit impasse.

BuzzFeed News is keeping track of which plan B different ministers appear to back. It's safe to say they don't all agree.

So far, some have suggested a second referendum. Others have called for a no-deal Brexit, some have insisted no deal must be stopped at all costs, while others want a series of "indicative votes" in parliament on what to do next.

This is a rolling list which we will update as and when ministers declare their positions.
