THERESA May will push for a strong trade deal with the US after Brexit when she meets Donald Trump in New York tomorrow.

The Prime Minister is holding talks with the President on Wednesday on the fringes of the United Nations General Assembly and will focus on future trading relations.

Ahead of the meeting, Mr Trump is chairing a UN Security Council session on counter-proliferation where Mrs May will speak about tackling the increased use of chemical weapons.

The one-to-one meeting later that evening will also include discussions on foreign affairs.

Mrs May told American reporters ahead of the visit that she did "trust" Mr Trump.

"Well, yes," she told CBS This Morning. "I mean, we work together. We have a special relationship. This is two people reflecting as leaders of their two countries - the relationship that those two countries have and have built up over a number of years.

"And as we work together - let me give you a very good example. You know, I spoke to President Trump after the Salisbury attack took place. He said he would expel Russian intelligence officers. He did it."

The PM’s meeting with Mr Trump follows a special Cabinet meeting on the Government’s policy on immigration post-Brexit, which is expected to be the centrepiece of Mrs May’s keynote speech to the Conservative conference next week.

Following the debacle in Salzburg and with suggestions senior colleagues would now push for a Canada-style trade deal instead of the Chequers Plan, No 10 insisted the Cabinet remained fully behind Mrs May's Brexit policy.

Downing St made clear she was sticking by her compromise blueprint and told her colleagues: “Now is the time to hold our nerve."

The continued defiance came as leading Tory Brexiteers urged the PM to grasp a "supercalifragilisticexpialidocious" Canada-style trade deal with the EU.

The call came from ardent Brexiteer Jacob Rees-Mogg at the launch event for a new Brexit blueprint by the free market Institute of Economic Affairs think-tank.

The charity is calling on ministers to seek a "basic" free trade agreement for goods and pursue "regulatory freedom and trade independence".

Mr Rees-Mogg, who leads the powerful Tory backbench European Research Group, said: "So much of what hear about these negotiations has been about managing decline, has been about how you have the least bad Brexit, this is about how you can have a fantastic Brexit that sets us up for the next generation and ensures our prosperity.

"This has been offered to us by the Commission, they have offered us the best trade deal they have ever done with any country ever in the world, so if you want to call it Canada plus, or super Canada or supercalifragilisticexpialidocious Canada, that is what is being aimed and its being offered."

The IEA's launch, which was also attended by former Brexit Secretary David Davis, saw proposals for a "Plan A+" deal with the EU which would see full reciprocal market access, no tariffs in goods including agriculture and maximum recognition of regulatory standards.

Mr Davis insisted it was time to "reset negotiations".

Mrs May's spokesman ruled out moving towards a Canada style deal, saying: "Given a standard free trade agreement could not prevent a hard border between Northern Ireland and Ireland, the EU's position is that their proposed Northern Ireland protocol would come into effect.

"So, the FTA would only apply to the Great Britain-EU relationship, with Northern Ireland effectively remaining in parts of the single market and customs union.

"The PM has repeatedly set out that we must protect the economic and constitutional integrity of the United Kingdom as a whole," he added.
