The European Commission says that some of the issues raised by British Prime Minister David Cameron to reform the EU are "highly problematic."

EU Commission spokesman Margaritis Schinas said Tuesday that some of Cameron's proposals for talks to make sure that Britain stays in the EU may be feasible but insisted others ranged from "difficult to worse."

He specifically latched on to proposals where freedom of movement would be limited by allowing the U.K. to restrict benefits for migrants from other member states.

"Some things which are highly problematic as they touch upon the fundamental freedoms of our internal market, direct discrimination between EU citizens clearly falls into this last category," Schinas said.
