EUROSCEPTIC Conservative MPs have warned that handing over money to Brussels following Brexit would be unacceptable to voters.

They are insisting the UK Government should not pay a so-called divorce bill to leave the European Union following suggestions Theresa May is prepared to pay €40 billion (£36bn) in order to strike a comprehensive free trade agreement with Brussels.

One MP has gone as far as to say Brussels should be giving money back to the UK instead.

The bill has been one of the main stumbling blocks in Brexit negotiations between Westminster and Brussels. It has been reported that the Government will only stump up the cash if the EU treats it as part of a deal on future relations, including any future trade agreement.

A senior Government source said that “no such figure has been agreed” while another Whitehall source dismissed it as “speculation”.

EU officials have said that trade talks are on hold until progress has been made on the financial settle ment, as well as the rights of citizens in Northern Ireland.

Conservative MP Peter Bone said that such a vast amount of money leaving the UK for Brussels would likely be blocked by Parliament.

“One of the prime reasons the UK voted to leave the EU was to stop sending them billions of pounds per year, so it would be totally bizarre to give the EU any money, let alone £36bn, given also that over the years that we have been in the EU or its predecessor we have given them, net, over £200bn,” he said.

“So if there was going to be any transfer of money then it should be from the EU to the UK.

“I think it would be very strange of Parliament to pay billions of pounds to leave an organisation that you have given hundreds of billions of pounds to and got nothing in return. That would be a very strange decision, so I don’t think it would happen.”

Jacob Rees-Mogg, MP for North East Somerset, added: “There is no logic to this figure, legally we owe nothing.”

The proposal would see Britain offer to make net payments to the EU of some €10bn a year for up to three years after Brexit as a partial down-payment on a final €40bn settlement.

Former Cabinet minister John Redwood completed the criticism of any future Brexit bill when he told LBC Radio: “Ministers would be quite wrong to be talking about any figures, we don’t owe them any money.

“It would be silly to be offering something when the EU is still not very willing to talk and is not coming up with anything constructive on its own side.

“The EU’s tactic is very clear. It’s divide and rule to try and get Britain negotiating with herself.”

A senior Whitehall source is quoted to have said the EU’s position is that the fee should be €60bn (£54bn), but the “actual bottom line” was €50bn (£45bn); the UK’s position was €30bn (£27bn) and “the landing zone is €40bn (£36bn) even if the public and politicians are not all there yet”.

Meanwhile, the SNP’s business spokesperson at Westminster has echoed warnings by business leaders over the UK government’s “haphazard” Brexit approach.

Drew Hendry MP added that the continued uncertainty over the future of EU workers living in the UK posed a “real and present danger” to business across the UK.

Speaking following the Institute of Directors calls on the UK Government to “engage properly on the most imminent risk to business from Brexit”, Hendry said that the Tories should end the internal squabbling and counter-briefings and instead work towards protecting the UK’s key businesses, jobs and economic opportunities.

Earlier in the week the Scottish Chambers of Commerce’s quarterly survey pressed the Tory government to seek an “early agreement on the rights of existing EU workers to live and work in the UK”. Hendry’s latest comments echoed this sentiment.

“We already know that an extreme Brexit has the potential to cost Scotland up to 80,000 jobs and £11.2bn per year, yet time and time again, warnings from the business community to the Tory government go ignored — causing uncertainty that is toxic to investment and growth,” he said.

“The uncertainty and threat is further fermented by the continued failure of the UK Government to seek an early agreement on the rights of existing EU workers, who are key to the success and growth of businesses.”
