Europe's leaders are still unclear on what the U.K. wants from the European Union (EU) as the Prime Minister David Cameron crosses the region tries to renegotiate his country's membership ahead of an in-out referendum.
While Cameron has said he is looking to repatriate powers back from the EU, cut red tape and restrict the numbers of migrants able to travel, work or claim benefits in the U.K., some of his fellow leaders are wondering why Britain wants to change something that benefits its economy.
"I don't know if what U.K. wants is lighter EU," Pierre Gramegna, Luxembourg's finance minister told CNBC Wednesday.
"They say (they want a) 'different' or 'more efficient' EU. What the EU commission has said and what we also subscribe to is that the four pillars of the EU -- the freedoms on which we built the EU – free flow of people, capital, goods and services – are essential."
"These pillars have been beneficial to all of us and particularly the U.K. so why change those pillars?," he said.
Cameron made a whistle-stop tour of five European capitals last week in order to drum up support for a reformed Europe but his attempts fell largely on deaf ears. The prime minister hopes is expected to attempt to speak to all 27 EU leaders individually before a European Council meeting at the end of June where he is expected to set out his reform plans in more detail.
