New life has been breathed into Theresa May's ailing Brexit deal after a cross-party group of MPs have proposed offering their support in return for a second referendum.

The new referendum would offer the British people a choice between the Prime Minister's deal and staying in the European Union.

The plan is being spearheaded by Labour MPs Peter Kyle and Phil Wilson alongside vocal Remainers in the Tory party such as Sarah Wollaston, Dominic Grieve and Anna Soubry.

Peter Kyle, MP for Hove, said that the amendment would be added to the withdrawal bill, but on the condition that if it passed through Parliament, there would be another referendum.

If Kyle's amendment was backed by a majority of MPs but the deal was rejected in the referendum, the UK would remain in the EU under current arrangements.

The cross-party initiative will also be a test of confidence that the Prime Minister has in her own deal: if the population supports May's Brexit deal, the UK would immediately initiate its departure on those terms, according to The Observer.

The Kyle initiative has won backing from vocal Tory Remainers including Anna Soubry MP

Kyle, 48, told The Observer: 'The beauty of this plan is that it holds attractions for both Leavers and Remainers.

For Leavers, if the deal is confirmed by the British people, it offers a definitive end to the withdrawal process with Brexit sealed once and for all. For Remainers, on the other hand, it offers the chance to make the case to stay in the EU to the public, based on facts not promises as before,' said Kyle.

'Remainers could vote for May's deal, or abstain, even though they might not like it, in the knowledge that they could campaign against it later in the referendum.

'The key is that Labour and Tory MPs could choose their own way of allowing the bill to pass, yet both will still be able to campaign in the referendum for their real objectives and their principles will remain intact'.

Sarah Wollaston MP said the plan was a 'very sensible way forward that I would be happy to support'

Labour MPs Kyle and Wilson say they have found a precedent in their idea based on how the Good Friday Agreement on Northern Ireland power-sharing passed through parliament in 1998.

While the initiative has won the backing of Anna Soubry MP and Sarah Wollaston MP said the plan was a 'very sensible way forward that I would be happy to support', the position of Kyle's own party leadership looks more uncertain.

Labour leader Jeremy Corbyn said his party would only back Theresa May's deal on five conditions including a permanent UK-wide customs union. However, Corbyn has insisted that he will not rule out a second referendum and that "all options are on the table".
