While Trump did not elaborate on what his US-UK trade comments following the Brexit deal, there are some limits to how and when a bilateral deal with the two nations can be shaped.
'Because right now if you look at the deal, they may not be able to trade with us. "Those who think that by rejecting the deal that they would have a better deal will be disappointed the first seconds after the rejection".
The report's authors, Arno Hantzsche, Amit Kara, and Garry Young, said "the main focus of our analysis is on how the government's proposed Brexit deal is likely to affect the economy, leaving aside the effect it might have on uncertainty".
Under the deal secured with European Union leaders on Sunday, Britain will leave the bloc in March with continued close trade ties, but the odds now look stacked against May getting it approved by a divided British parliament.
May has since been on the offensive and revived Vote Leave's controversial claim that Brexit will benefit the National Health Service (NHS) in a bid to sell her freshly-signed divorce deal.
In todays prices, this would amount to a loss of £1,000 for each British person every year by 2030 and would mean the overall United Kingdom economy would shrink by 3.9 per cent each year.
The MEP for Gibraltar says the United Kingdom should have a vote between Theresa May's Brexit deal and remaining in the EU. May and politicians in Northern Ireland have said they would refuse any solution that would effectively create a hard border in the Irish Sea by treating Northern Ireland differently to the rest of the UK.

May, when asked by reporters, if she would consider stepping down if the deal fails in Parliament, May said "this is not about me".
Those called to open the questioning included the ERG's chairman Jacob Rees-Mogg, former chairman Steve Baker and deputy chairman Mark Francois, all of whom have published letters of no confidence in the Prime Minister in the last fortnight.
There is little evidence Britain's embattled prime minister will have sufficient support to win legislative endorsement of the deal in a House of Commons vote next month.
Dutch Prime Minister Mark Rutte said the deal - the product of a year and a half of often grueling negotiations between Britain and the European Union - was regrettable, but acceptable.
That seems likely, at least as of Sunday, since the European Union -approved agreement is opposed by the Labour, Liberal Democrats, SNP, and DUP parties, as well as more than 80 MPs in May's Conservative (Tory) party (and she can't lose more than six). "It is the best possible deal".
But with just two weeks to go before Parliament delivers its crucial verdict that could make or break the deal, May's strategy appears to have mostly failed.
"The European Council invites the Commission, the European Parliament and the Council to take the necessary steps to ensure that the agreement can enter into force on 30 March 2019, so as to provide for an orderly withdrawal", the European Council said in a news release.
