The deal Britain is seeking with the European Union would be beneficial to other EU members too, British Prime Minister David Cameron said in Denmark on Friday.
"The sort of Europe I believe in has got to be flexible enough to deal with the concerns of countries, large and small," Cameron told reporters after meeting his Danish counterpart, Lars Lokke Rasmussen.
Denmark was the latest stop in Cameron's efforts to muster support ahead of an EU summit in Brussels on February 18-19.
Rasmussen said Denmark supported proposals presented by EU President Donald Tusk, and noted they were akin to the opt-outs Denmark secured in 1993 that had "served Danish interests very well."
Denmark - like Britain - does not use the joint euro currency.
"The paper proposed is a solid answer to what we need," the Danish leader said of Tusk's proposals, adding he would be "as supportive as possible."
Cameron has proposed a referendum on British EU membership by the end of 2017.
"This package of measures, ... if we can agree to the detail of it, if, where possible, we can improve it, it would be good for Britain and other European countries too," Cameron said. Earlier Friday, Cameron visited Warsaw for talks with Polish leaders.
