Theresa May and her cabinet are looking for ways to bring her EU withdrawal agreement back to the commons for a fourth attempt at winning mps’ backing.
The PM said the UK would need “an alternative way forward” after her plan was defeated by 58 votes on Friday.
MPs from all parties will test support for other options during a second round of “indicative votes” on Monday.
But government sources have not ruled out a run-off between whichever proves most popular and the pm’s brexit plan.
Labour leader Jeremy Corbyn has called on Mrs May to change her deal or resign immediately, while northern Ireland’s dup – which has propped up Mrs May’s minority government – also continues to oppose the deal.
The government has so far failed to win over 34 conservative rebels, including both retainers and Tory Brexiteers who say the deal still leaves the UK too closely aligned to Europe.
