Theresa May has invited Conservative MPs who are trying to soften her stance on Brexit into Downing Street for peace talks this evening.

The Independent understands around a dozen backbench MPs including key figures who have sought to change Ms May’s position have been given the opportunity to speak with her.

It comes after a keynote speech last week was publicly welcomed by MPs from both sides of the Brexit debate in the Conservatives, but with underlying tensions continuing to strain party.

Ms May still faces a major challenge to her authority from a rebel amendment which seeks to force her to keep the UK in a customs union with the EU after Brexit.

One backbencher told The Independent: “The ‘mutineers’ have been invited in to have a chat with the Prime Minister.

“The speech went some way to lowering the heat for now, but they clearly still have a lot of concerns about what is happening.

“Anna Soubry’s amendment to the Trade Bill is obviously causing some concern.”

Theresa May calls her Brexit plan 'practically-based' and therefore 'credible'

Broxtowe MP Ms Soubry’s amendment could well be supported by the Labour party, raising the prospect of Ms May suffering a major Commons defeat and potentially having her hands tied in negotiations with Brussels.

The next stage of the Bill is yet to be scheduled by the Conservatives, with whips attempting to quell any rebellion ahead of allowing the amendment to go to a vote.

A Downing Street spokesman said they would not comment on private meetings, but underlined that the Prime Minister welcomes the opinion of all her MPs.

She appeared before the Commons on Monday to reiterate Brexit commitments which she outlined in her speech on Friday.

Repeating words from her speech in the chamber, Ms May said: “We cannot escape the complexity of the task ahead.”

One possible post-Brexit immigration scheme could struggle to channel workers towards less attractive roles - while another may heighten the risk of labour exploitation, a new report warns. PA The biggest issues facing UK on leaving EU Customs union A key point in the negotiations remains Britain's access to, or withdrawal from, the EU customs union. Since the referendum there has been hot debate over the meaning of Brexit: would it entail a full withdrawal from the existing agreement, known as hard Brexit, or the soft version in which we would remain part of a common customs area for most goods, as Turkey does? No 10 has so far insisted that “Brexit means Brexit” and that Britain will be leaving the customs union, but may be inclined to change its position once the potential risks to the UK’s economic outlook become clearer.

To ensure borderless travel on the island, the countries must be in regulatory alignment and therefore adhere to the same rules as the customs union. In December, the Conservative Party’s coalition partners, the DUP, refused a draft agreement that would place the UK/EU border in the Irish Sea due to its potential to undermine the union. May has promised that would not be the case and has suggested that a “specific solution” would need to be found. Getty The biggest issues facing UK on leaving EU Transition period Despite protests from a small number of Conservative MPs, the Government and the EU are largely in agreement that a transitional period is needed after Brexit. The talks, however, have reached an impasse. Though May has agreed that the UK will continue to contribute to the EU budget until 2021, the PM wants to be able to select which laws made during this time the UK will have to adhere to. Chief negotiator Michel Barnier has said the UK must adopt all of the laws passed during the transition, without any input from British ministers or MEPs.

May insists that those who arrive during the transition period should not be allowed to stay, whereas the EU believe the cut-off point should be later.

Infighting within the Cabinet has prevented a solid position from being reached, with some MPs content that "no deal is better than a bad deal" while others rally behind single market access. The EU has already confirmed that access to the single market would be impossible without the UK remaining in the customs union.

However the UK cannot make trade agreements with another country while it is still a member of the EU, and the potential loss of trade with the world's major powers is a source of anxiety for the PM. The EU has said the UK cannot secure trade deals during the transition period.

The EU has refused to give British banks passporting rights to trade within the EU, dashing hopes of a special City deal.

She went on: “We must build a new and lasting relationship while preparing for every scenario. But with pragmatism, calm and patient discussion, I am confident we can set an example to the world.

“Yes, there will be ups and downs over the months ahead, but we will not be buffeted by the demands to talk tough or threaten or walk out – and we will not give in to the counsels of despair that this simply cannot be done, for this is in both the UK’s and EU’s interests.”

The shift in her rhetoric from the days of “Brexit means Brexit” to a more realistic tone, was welcomed by those MPs on her own benches who feared the UK was veering towards a hard Brexit.

But they continue to harbour concerns that the approach she is setting out may be so complex as to be unfeasible and too costly to achieve, let alone persuade the EU of.
