British Prime Minister David Cameron on Thursday appealed to Germany to help him achieve the European Union reforms he needs to persuade Britons to remain in the 28-nation bloc, AFP reports.

Britain is expected to hold a referendum on whether to remain in the EU by the end of 2017, and Cameron is currently in Germany to renegotiate ties with the union to help counter burgeoning British euroscepticism.

"Support for our membership has declined over many years. So I am negotiating changes which will address the concerns of the British people," Cameron wrote in an article for Germany's Bild newspaper.
