What next if MPs reject Brexit deal?

london — Prime Minister Theresa May appears likely to lose a historic vote on the Brexit deal she has struck with EU leaders in a crucial parliament vote on Tuesday.

Defeat in the House of Commons is almost certain to lead to either a no-confidence vote from the opposition or a leadership challenge from within her own Conservative Party.

Here are some of the most probable scenarios:

The prime minister could face demands to head to Brussels and attempt to extract concessions before putting the deal to a second vote by parliament.

EU leaders have rejected the prospect of renegotiating the withdrawal agreement itself but European sources speaking privately say tweaks in the accompanying declaration on post-Brexit ties might be possible.

May is headed to Brussels anyway for a summit with 27 fellow EU leaders on Thursday and Friday. “Theresa May is going to come

to the European summit on December 13 and 14 and ask for a re-negotiation and the 27 are going to say no, the texts are agreed,” an informed European source told AFP on condition of anonymity. “They are then going to fall back on a protocol or a clarification on a point seen as important to then go back to parliament.”

With MPs having more of a say in the process, it is possible they could push for a “plan B”, which

would see Britain adopt a softer Brexit, such as staying in the EU’s satellite trading bloc the European Economic Area — the so-called Norway option.

Although being in the single market would require maintaining freedom of movement of European Union citizens into Britain this approach is considered more likely to command a majority in parliament and potentially pass a second vote. —
