The minister responsible for Brexit has told the EU to "get real" and reach a deal with the UK.

Dominic Raab also said EU chiefs had disrespected Theresa May with "jibes" at a recent summit.

He said the UK would leave without a deal rather than be "bullied" into signing a "one-sided" arrangement.

Meanwhile EU figures hit back after Foreign Secretary Jeremy Hunt likened it to a Soviet-era prison, comments diplomats called "insulting".

In a speech to the Conservative conference on Sunday, Mr Hunt compared what he said were the EU's attempts to stop members leaving with the actions of the Soviet Union during the Cold War.

His words were criticised by a number of European politicians and diplomats while a European Commission spokesman suggested everyone "could benefit from opening a history book from time to time".

Speaking in Birmingham on Monday, Mr Raab said the government's proposed deal with the EU was not "perfect" but he urged Tory Eurosceptics who are campaigning for the plan to be ditched to get behind it.

And Chancellor Philip Hammond predicted that there would be an economic bounce if and when a Brexit deal was agreed by the UK and the EU.

He reminded people saying that a deal could not be struck that people had had the same scepticism about the electric light bulb ever working.

With less than six months to go before Brexit day, the UK and the EU have not yet reached a deal on how separation will be managed and what their new relationship will look like.

Mr Raab said that if the EU insisted on trying to "lock us in via the back door" of its customs union and single market, the UK could be left with "no choice" but to leave without a deal.

The "whole of the government machine is busy preparing for no deal" - not because they want it to happen or because it's likely, but "because it might happen", he said.

He dismissed "lurid predictions from the prophets of doom" about no-deal, including planes being grounded and ports blocked.

Even if the UK did not reach an agreement with the EU, he said: "I find it hard to believe that they would, for narrow political ends, seek to punish Britain in such a crass and counterproductive way."

Mr Raab criticised the EU over its reaction to Theresa May's proposals at last month's summit in Salzburg.

"Our Prime Minister has been constructive and respectful," he said.

"In return we heard jibes from senior leaders, and we saw a starkly one-sided approach to negotiation."

What is wrong with Chequers?

Brexiteers feel it keeps the UK far too close to Brussels and doesn't fulfil the Leave campaign's promise during the 2016 referendum campaign to "take back control".

EU leaders have rejected the plan because they believe it would undermine the single market by allowing the UK to "cherry pick" from EU law.

Theresa May says the ball is now in the EU's court and she wants a more detailed response from them on their objections.

The government has said it will not agree to anything that divides Northern Ireland from the rest of the UK nor makes the country a member of the European Economic Area like Norway.

Johnson's running joke?

One of the most vocal critics of the government's Brexit approach has been former foreign secretary Boris Johnson, who branded Theresa May's plan "deranged" in a newspaper interview at the weekend.

Despite not being in Birmingham, Mr Johnson made an eye-catching appearance as he was photographed running through fields near his Oxfordshire home.

Given that Mrs May famously said her naughtiest moment was running through fields of wheat as a child, some pundits are wondering whether this was an attempt to "troll" the PM by the former Leave campaign frontman, who resigned in protest at the Chequers plan in July.

Row over Hunt's comments

Jeremy Hunt has seemingly provoked a diplomatic row after accusing the EU of seeking to punish the UK in order to "keep the club together".

In Sunday's speech, he recalled a visit to Latvia earlier this summer and the role that the UK and others played in helping it transition from Soviet rule to becoming a modern democracy and market economy.

"What happened to the confidence and ideals of the European dream?", he asked. "The EU was set up to protect freedom. It was the Soviet Union that stopped people leaving."

Guy Verhofstadt, the European Parliament's Brexit co-ordinator, tweeted that the remarks were "outrageous and offensive".

And EU Commissioner Vytenis Andriukaitis suggested Mr Hunt needed a history lesson.

Hammond's low wages warning

Also on the conference stage on Monday, Mr Hammond warned that slow wage growth and job insecurity meant too many people feared they were being left behind.

He announced the government's intention to increase the number of people who can access science and technology courses and spend about £30m on encouraging big business to mentor small firms.

His plans also included a £125m package allowing large employers to transfer up to 25% of their apprenticeship levy funds to businesses in their supply chain from April next year.

The apprenticeship levy is a tax on large companies intended to pay for training at smaller companies, but uptake of the new policy has been slow.

Mr Hammond rejected suggestions that Brexit had caused an irreparable rift between his party and business, telling activists the Conservatives were and "always will be the party of business".
