UK Prime Minister David Cameron sent European Council President Donald Tusk a letter laying out his EU reform requirements on Tuesday, marking the formal beginning of a campaign to renegotiate the United Kingdom’s EU membership.

MOSCOW (Sputnik), Daria Chernyshova – UK Prime Minister David Cameron’s EU membership reform proposals are designed to “fool” the British public into voting to stay in the bloc, the UK Independence Party (UKIP) spokeswoman for small business told Sputnik on Tuesday.

“Cameron’s idea of a third way is simply a charade designed to fool the British people into voting to stay in a virtually unreformed EU,” Margot Parker said, arguing that “there is no two-speed Europe.”

Parker predicted that Britain’s “pesky” renegotiation strategy, comprising four sovereignty, monetary, competitiveness and free movement demands, would have no impact on the the European Union’s “ever closer union end game.”

“Britain is either fully in or fully out,” she stressed.

The life that a Brexit would “breathe back” into British small business “could not be understated,” Parker added.

The 19 members of the European monetary union, the eurozone, will "club together" against the United Kingdom as it reviews its relationship with the European Union, she said.

"It is clear that the 19 members of the eurozone are going to club together to make sure that they get the best deal possible and Britain will certainly get a raw deal because of this. In the eyes of the EU there is only one currency of Europe and that is the euro."

Parker, a European Parliament lawmaker, questioned whether other EU member states or institutions would have the "appetite" to introduce a set of binding principles guaranteeing parity between euro and non-euro countries.

Cameron emphasized the notion of a "union with more than one currency" when introducing the four-step EU reform plan earlier in the day, urging "flexibility between those inside and outside the eurozone."
