May rebukes Trump as she bids to sell Brexit deal

Prime Minister May headed to Wales and Northern Ireland, hours after US President Trump said it seemed like a "great deal" for the European Union that could block Britain from forging its own trade agreements with the United States.

May has two weeks to convince the public, and, crucially, a divided parliament, before the December 11 vote in the House of Commons that risks ending in a humiliating defeat and sinking the deal.

Trump suggested May had made a mistake by signing an agreement that might impede a future trade deal between London and Washington.

"Sounds like a great deal for the EU," he said at the White House, adding: "We have to take a look at seriously whether or not the UK is allowed to trade".

"As the deal stands, they may not be able to trade with the US and I don't think they want that at all. That would be a very big negative for the deal," said the president, who is close to leading Brexiteers in the UK.

"I don't think that the prime minister meant that and hopefully she'll be able to do something about that."

Starting her tour in Builth Wells in central Wales, May insisted Trump had not rained on her parade.

"We will have an independent trade policy and we will be able to negotiate trade deals with countries around the rest of the world," May.

"As regards the United States, we have already been talking to them about the sort of agreement that we could have in the future.

"It will no longer be a decision taken by Brussels. We will have control of that and we will strike trade deals that will enhance our prosperity, enhance our economy and bring jobs to the UK."

Her spokesman said there were no plans for one-to-one talks between May and Trump at the G20 summit in Buenos Aires this weekend.

The pound was down about 0.3 per cent against the dollar while London's FTSE 100 share index was down 0.4 percent in early afternoon trade.

May on Sunday closed 17 months of complex talks with Brussels by sealing Brexit arrangements with the 27 other EU heads of state and government.

But this tortuous chapter on ending Britain's 45-year involvement in the European project was just the beginning of another struggle.

May runs a minority Conservative government and opposition parties, as well as many of her own MPs, are against the deal.

Some Brexiteers think it keeps Britain shackled to Brussels while pro-EU lawmakers think the terms are worse than staying in the bloc and want a second referendum.

Opposition Labour party leader Jeremy Corbyn called the deal "an act of national self-harm".

May, who ducked televised debates during the 2017 snap general election, challenged Corbyn to a TV contest, nominally planned for December 9.

"I am ready to debate it with Jeremy Corbyn because I have got a plan. He hasn't got a plan," May was quoted as saying by The Sun newspaper.

A Labour spokesman said: "Jeremy would relish a head to head debate with Theresa May about her botched Brexit deal and the future of our country."

In London, Brexit figurehead Nigel Farage launched a billboard campaign reading "Welcome to the worst deal in history".

A few streets away, anti-Brexit youth movement Our Future, Our Choice rolled out a campaign bus urging MPs to heed their voices.

Meanwhile in Luxembourg, lawyers for a group of Scottish politicians argued before the top European court that the British parliament should have the unilateral power to halt the countdown to Brexit, set for March 29.

A Scottish court has referred the case, which hinges on whether London could simply revoke Britain's "Article 50" EU withdrawal process, to the European Court of Justice.

The British government argues that the case is a political tactic by pro-EU opponents.

A court source told AFP that the decision could well be made before the end of the year, but the judges must first decide if the ECJ even accepts jurisdiction in the case.
