Some of Cameron's EU Reform Proposals 'Highly Problematic' – EU Commission

Some of the issues put forward by British Prime Minister David Cameron in a bid to reform the country's relations with the European Union are "highly problematic," a European Commission spokesman said Tuesday.

MOSCOW (Sputnik) — Earlier in the day, Cameron sent European Council President Donald Tusk a letter laying out his EU reform requirements, formally launching a campaign to renegotiate the United Kingdom’s EU membership.

"Prima facie we see a number of elements which appear to be feasible, like finding ways to increase the role of national parliaments, some issues which are difficult, like ever closer union and relations between the euro ins and outs, and some things which are highly problematic as they touch upon the fundamental freedoms of the internal market," Margaritis Schinas stated at a news conference.

Cameron’s four key demands included protection of the single market for the United Kingdom and others outside the eurozone, stimulation of the competitiveness of the entire European Union, exemption for London from an ever-closer union, removing violations restricting the right to freedom of movement and enabling countries to control migration from the European bloc.

According to the UK prime minister, he will campaign 'heart and soul' to stay in Europe if his reforms are taken into consideration.

Britain’s exit from the European Union – the so-called Brexit – will be voted on in a referendum by the end of 2017, as promised by Cameron during the pre-election campaign in spring.

Ahead of the vote, Cameron decided to renegotiate the terms of the country's membership in the bloc, including on migration and commerce policies.
