This is the first policy brief out of numerous policy briefs which Cyprus 2015 will be producing. The briefs are designed to influence policy discourse and public understanding. This policy brief focuses on Negotiating the Core Issues: the Importance of Greek Cypriot and Turkish Cypriot public opinion. The timing and focus of this publication are strategic since it was shared with the Turkish Cypriot and Greek Cypriot Leaders just before their 3-day meeting with Ban Ki-moon.
