SMUG Eurocrats believe Britain would face such a chaotic meltdown within the first week of a no deal Brexit that it would have little choice but to return to the negotiating table.

Senior diplomats told The Sun that Brits would face “no flights to and from the UK, no ships, no economic activity and no financial transactions” if we failed to agree a deal before we leave the bloc next March.

One ambassador predicted the chaos for businesses and ordinary people in the UK would get so bad the situation would quickly become untenable for the Government.

And a senior EU official said Brussels negotiators were banking on it being such a disaster that the “cycle of negotiations and the political dynamics will be taken over by the real world”. But leading Brexiteer Jacob Rees-Mogg dismissed the “delusional”.

He hit back at Brussels, telling The Sun: “It is wishful thinking by a EU establishment that has failed to notice that its grand scheme has failed economically, is devoid of democratic support and is increasing unpopular across the continent.

EU sources also questioned Brexit secretary Dominic Raab’s upbeat assessment of how the UK would cope in the first few weeks of a no deal outcome. One said they “wouldn’t count on” his reassurance that Brits will still be able to enjoy a BLT sandwich in such a scenario.

Last week the Government published a slew of notices warning people and businesses how to prepare for a crash out situation in March next year.

Announcing them, Mr Raab dismissed suggestions the army and Air Force would have to be deployed to secure food and medicine supplies as “scare stories”. And in a bizarre pledge, he said Brits will “still be able to enjoy a BLT after Brexit”.

But asked whether the UK Government could survive the first few days of a no deal exit, an EU ambassador told The Sun: “It’s not possible to have a no deal. There would be a massive outcry.

“With even a no deal for one week, with no flights to and from the UK, no ships, imagine the economic loss of one week of no economic activity, no personal activity, no financial transactions. That would already be a disaster.”

The diplomat added that Britain’s sluggish economic growth over the past year meant it was already “falling behind more and more” compared to the rest of the continent.

The EU Commission has slashed its growth forecast for the UK to just 1.3 per cent for 2018, the joint lowest rate alongside struggling Italy.

And EU officials believe that business pressure on Ministers to reach a compromise and avoid a crash out will crescendo in the next few months.

A senior EU official told The Sun: “The moment the markets understand this is going in the wrong way, the cycle of negotiations and the political dynamics will be taken over by the real world.

“In a few months the UK will have a credibility issue. The moment economic operators understand this is going wrong there will be events on the ground.”

Meanwhile a former EU chief sparked outrage yesterday by claiming a no deal Brexit would trigger the break-up of the UK.

Former European Council President Herman Van Rompuy said: “We could end up with a situation in which the EU27 becomes more united and a United Kingdom less united. This talk about a ‘no deal’ is the kind of nationalist rhetoric that belongs to another era.”

The Sun Says THE Eurocrats are losing the plot. We’re used to their regular predictions that Britain will turn into the 10th circle of hell once we leave the EU. But even we’re taken aback by the ridiculous warning that we’ll have “no economic activity” the day after a clean break Brexit. These bizarre forecasts show the arrogance of those who rise to the top of the European tree. They genuinely believe that without their flag, their bureaucracy and their anthem that the continent will just fall apart. And it reveals their motives in the Brexit negotiations. To punish us, and send a message to anybody thinking of heading for the exit door – no matter how disastrous it is for the European economy. How are we supposed to negotiate in good faith? They can barely conceal their hope that the UK is going to slip into anarchy. The Government must continue to plan for a clean break. And treat everything Brussels says with not so much a pinch but a whole bucketload of salt. Meanwhile, for all their cocksure bravado, the EU is in all sorts of trouble. Unelected bosses in Brussels are in open warfare with the elected leaders of Poland and Hungary and are now fixing for a fight with Italy, too. Even the EU’s so-called ‘triumph’ in Greece will ring hollow to the 40% of youngsters there who are still out of work. Some ardent Remainers at home are still hoping that Britain might change its mind on leaving. But Brussels keeps proving that we’re better off out.
