EU Deal 'Irreversible', Insists David Cameron

David Cameron has insisted a finalised EU reform deal would be "irreversible" as the UK would have a veto.

He was speaking after the European Parliament President Martin Schulz told Sky News that everything could be reversed, including legally binding decisions.

His comments were likely to prove unhelpful to the Prime Minister as he sought to rally support for the proposed reforms.

But during a visit to meet with his counterpart in Copenhagen, Mr Cameron said while it was technically reversible, Britain would need to agree to it.

Mr Schulz had told Sky News: "Nothing in our lives is irreversible.

"Therefore legally binding decisions are also reversible - nothing is irreversible.

"But in politics, when 28 heads of states and governments and the European institutions together on the 19 February agree about a deal, the deal is done."

Mr Cameron has been engaged in a frantic diplomatic efforts in Europe as he seeks to drum up support for the draft deal hammered out with Brussels.

Pressed about Mr Schulz's remarks during a visit to Copenhagen, Mr Cameron said of the deal: "If it is agreed, it will be agreed as a legally binding treaty deposited at the United Nations.

"It would only be reversible if all the 28 countries, including Britain, agreed to reverse it.

"Given its the treaty that Britain wants there's no way we are going to agree to reverse it.

"So while you can argue it's technically reversible if we agreed to reverse it, it is not in fact reversible

"It will be legally binding and irreversible."

An EU source told Sky's Faisal Islam that Friday's talks between EU officials were "constructive", but said "difficult negotiations" lie ahead.

In his interview with Sky News, Mr Schulz also made his pitch for UK voters to back remaining in the EU.

He said: "Together we are strong.

"Let's organise this effectively, let's reduce bureaucracy and make the European Union more transparent.

"But to survive in that worldwide competition in the 21st century...we need to combine our common power, our common strength.

"Therefore, to stay in is in the national interest."

While he acknowledged there were some MEPs, frustrated with Britain, who argued it should leave the EU, he said this was "a big error" and he would be fighting for it to stay.

Earlier, an opinion poll indicated the PM's proposed changes to the UK's relationship with Brussels had failed to win over the public.

A YouGov poll for The Times carried out two days after the outline plan was revealed found 45% intended to vote Out - up three points on the previous week.

Some 36% of voters want Britain to remain in the 28-strong bloc, while 19% are undecided.

This represented a record lead for the Out campaign.
