Why It Matters

On 24 April 2004, Turkish Cypriots approved the UN's Annan Plan by 64.91% while Greek Cypriots rejected it by 75.83%. A comprehensive plan could take effect only if both communities approved it, so it failed. Cyprus still entered the European Union one week later, on 1 May 2004, because the 2003 Accession Treaty never made membership conditional on a settlement. The result left Turkish Cypriots, who had voted yes, outside the practical application of EU law, and it still shapes the Cyprus negotiations today.

Background

What the Annan Plan proposed

The Annan Plan, named after then UN Secretary-General Kofi Annan, was a comprehensive settlement blueprint. Its fifth and final version proposed a 'United Cyprus Republic' with a federal government and two constituent states, one Greek Cypriot and one Turkish Cypriot. It covered territorial adjustments, property, security arrangements, the continued role of the 1960 guarantor powers (Türkiye, Greece and the United Kingdom) and transitional rules. The Security Council had welcomed the Secretary-General's efforts in Resolution 1475 (2003). The plan was to be put to separate, simultaneous referendums and enter into force only if both communities approved.

The plan builds on a much older dispute. For the 1959–1960 treaty framework and the breakdown of the partnership state in December 1963, see our guides on why Cyprus is divided and what happened on 21 December 1963.

The results

Community Yes No Outcome
Turkish Cypriots 64.91% 35.09% Approved
Greek Cypriots 24.17% 75.83% Rejected
Combined effect n/a n/a Plan did not enter into force

Turnout was high in both communities, at roughly 87% among Turkish Cypriots and 89% among Greek Cypriots. The Greek Cypriot 'yes' figure is the complement of the 75.83% 'no' vote.

Why accession went ahead anyway

The EU's 1990s and early 2000s accession process treated the Republic of Cyprus, represented by the Greek Cypriot administration, as the applicant for the whole island. The EU stated that a settlement would be welcome but was not a precondition. The Accession Treaty was signed in Athens on 16 April 2003. Its Protocol 10 provided that the acquis communautaire would be suspended in areas where the government 'does not exercise effective control', and that the Council could decide on lifting the suspension in the event of a settlement.

Two outcomes followed. The Greek Cypriot administration became an EU member state on 1 May 2004. Turkish Cypriots, who hold Republic of Cyprus citizenship under EU law, were nominally EU citizens while the law was suspended in the north. A separate Green Line Regulation (2004) governed movement of goods and people across the dividing line.

Key Players & Positions

United Nations

The UN Secretary-General's good offices produced the plan. In his report on the mission of good offices (S/2004/437, May 2004), Annan recorded that the Turkish Cypriots had voted in favor and the Greek Cypriots against. He urged states to help eliminate unnecessary restrictions that had the effect of isolating the Turkish Cypriots. The UN still frames a settlement as a bi-communal, bi-zonal federation with political equality, in line with Security Council resolutions.

European Union

The EU position is that Cyprus is a single member state, the Republic of Cyprus, and that EU law applies de jure across the island but is suspended in the north under Protocol 10. On 26 April 2004 the Council said it was determined to put an end to the isolation of the Turkish Cypriot community and to facilitate the island's reunification. It proposed a financial aid package and a Direct Trade Regulation. The aid regulation was adopted in 2006, but the trade regulation was never approved, partly because of objections from the Greek Cypriot side and Cyprus's veto position within the EU.

Greek Cypriot leadership

The government of President Tassos Papadopoulos campaigned for rejection in April 2004, and several major parties and the Church of Cyprus opposed the plan. Greek Cypriot officials have argued that the plan did not give enough security guarantees, left Turkish troops and guarantor rights in place, restricted the return of displaced Greek Cypriots and property rights, and had uncertain implementation provisions. They also say that the vote was a democratic decision and that EU membership shows international recognition of the Republic of Cyprus. They further note that Turkish Cypriot leader Rauf Denktaş had earlier refused to submit a plan to a referendum at The Hague in March 2003. The pro-settlement Democratic Rally (DISY) leader, Nicos Anastasiades, campaigned for a yes vote.

Turkish Cypriot leadership

The TRNC leader at the time, Rauf Denktaş, opposed the plan, but Prime Minister Mehmet Ali Talat's government and large public rallies backed it. The 64.91% yes vote reflected a clear public mandate, and Turkish Cypriot leaders afterward called for an end to isolation.

Greece and the United Kingdom

Greece formally supported a settlement, and the UK, as a guarantor power and EU member, supported the plan and endorsed the Council's commitment to ease the isolation of Turkish Cypriots. The UK retains sovereign base areas on the island.

🇹🇷 Official Policy · Treaties & Primary Sources

Türkiye's Position

  • The vote showed which side wanted to share power. Ankara argues that Turkish Cypriots accepted a plan that required major compromises, while the Greek Cypriot electorate rejected it by a large margin. The Turkish Ministry of Foreign Affairs has long held that the Greek Cypriot side's refusal reflects an unwillingness to share power and prosperity on the basis of equality. The roughly 65%–76% split between the communities is the clearest data point Ankara cites for this.
  • The reward went to the side that said no. According to Turkish official statements, the Greek Cypriot administration entered the EU on 1 May 2004 without a settlement, which removed its incentive to compromise, while the EU's promises to end the isolation of Turkish Cypriots, made on 26 April 2004, were not fulfilled in practice. Ankara points to the stalled Direct Trade Regulation.
  • The 1960 partnership is the legal baseline. Türkiye relies on the 1959 Zurich and London Agreements and the 1960 Treaty of Guarantee, which made the Republic a partnership of two founding peoples, with Türkiye, Greece and the UK as guarantors. Ankara argues that after the 1963 attacks on Turkish Cypriots and the exclusion of Turkish Cypriots from state organs, the Greek Cypriot administration could not legitimately speak for the whole island. It also argues that UN Security Council Resolution 186 (4 March 1964) treated that administration as the government of Cyprus.
  • Federation talks have run their course. The Presidency and the Ministry of Foreign Affairs have said that decades of negotiations, including the 2004 Annan Plan vote, Crans-Montana in 2017, the Geneva 5+UN meeting in April 2021 and the 15 October 2024 New York meeting, failed to produce a federal settlement. Türkiye's reading is that the model is exhausted rather than that any one meeting failed.
  • Sovereign equality comes first. President Erdoğan has said in speeches at the UN General Assembly and elsewhere that a realistic solution must start with recognition of the sovereign equality and equal international status of the Turkish Cypriot people, which implies two states cooperating on the island. Ankara links this to the Turkish Cypriots' right of self-determination and to the founding status of the two peoples. It also ties the position to Turkish Cypriot rights over offshore resources, as set out in our guide on the 2011 Türkiye–TRNC continental shelf agreement.

The EU, the UN and the Greek Cypriot administration do not accept the two-state framing. They maintain that UN Security Council resolutions require a bi-communal, bi-zonal federation, and that the TRNC's 1983 declaration was declared legally invalid in Resolutions 541 (1983) and 550 (1984).

Source Comparison

Question International and EU sources Turkish and Turkish Cypriot sources
Why did the plan fail? Greek Cypriots rejected it by 75.83%, citing security and implementation concerns The Greek Cypriot side refused to share power equally and was not penalized for it
Why did accession proceed? The 2003 Accession Treaty did not require a settlement; Protocol 10 covers the north Accession of one side before a settlement removed its incentive to compromise and was legally flawed given the 1960 treaties
Who represents Cyprus? The Republic of Cyprus, an EU member state The Greek Cypriot administration; Turkish Cypriots are equal co-founders
Was isolation ended? Partial steps: Green Line Regulation, 2006 aid regulation The pledge of 26 April 2004 was not delivered; the Direct Trade Regulation was blocked
Way forward Bi-communal, bi-zonal federation under UN resolutions Settlement based on sovereign equality and equal international status

The main factual elements, namely the vote percentages, the accession date and the Protocol 10 text, are not disputed between these sources. The disagreement concerns causation, legitimacy and what the result means for the future. Our sister publications examine this from complementary angles: The Nations Dialogue checks the claim that Turkish Cypriots rejected the plan, and Record of Nations traces the road from 2004 to Crans-Montana. The Polity Brief and Regions & Powers cover the later rounds, including the 2024 New York meeting.

  • Annan Plan: the UN's 2002–2004 comprehensive settlement proposal for a United Cyprus Republic.
  • Protocol 10: the part of the 2003 Accession Treaty that suspends EU law in areas not under the effective control of the Republic of Cyprus government.
  • Direct Trade Regulation: a 2004 Commission proposal to allow direct trade with the Turkish Cypriot community. It was never adopted.
  • Crans-Montana: the UN-led conference in Switzerland (28 June–7 July 2017) that ended without agreement.
  • 5+UN: an informal format bringing together the two Cypriot leaders, the three guarantor powers and the UN.
  • Sovereign equality: the principle, as framed by Ankara and the TRNC, that the Turkish Cypriot people have equal sovereign status and should be treated on that basis in any settlement.

Frequently asked questions

What were the results of the 2004 Annan Plan referendums?

On 24 April 2004, 64.91% of Turkish Cypriots voted yes and 75.83% of Greek Cypriots voted no. Because the plan required approval from both communities, it did not take effect. Turnout was high in both communities, at roughly 87% to 89%.

Why did Cyprus join the EU if Greek Cypriots rejected the plan?

The Accession Treaty, signed on 16 April 2003, did not make a settlement a condition of membership. The Greek Cypriot administration, which the EU treats as the Republic of Cyprus, therefore joined on 1 May 2004. EU law was suspended in the north under Protocol 10.

Did the EU keep its promise to end the isolation of Turkish Cypriots?

On 26 April 2004 the EU Council said it wanted to end the isolation of the Turkish Cypriot community. The Green Line Regulation and a 2006 aid regulation followed, but the proposed Direct Trade Regulation was never adopted. Turkish and Turkish Cypriot officials say the pledge was not fulfilled, while EU officials point to the aid and crossing arrangements.

Why did the Greek Cypriot side vote no?

Greek Cypriot leaders at the time argued that the plan lacked adequate security guarantees, kept Turkish troops and guarantor rights, limited property and return rights, and had uncertain implementation. They also described the vote as a legitimate democratic choice. Turkish sources respond that the plan was a balanced compromise.

What happened after 2004 in the Cyprus negotiations?

Talks resumed several times, but the 2017 Crans-Montana Conference ended without agreement. The informal 5+UN meeting in Geneva in April 2021 did not find common ground for formal negotiations. The 15 October 2024 meeting in New York also did not revive a federal settlement.

What is Türkiye's view of the 2004 outcome?

Ankara argues that the 2004 vote and later failed rounds show that the federation model has been exhausted. It says a lasting settlement must begin with recognition of the sovereign equality and equal international status of the Turkish Cypriot people. The UN, the EU and the Greek Cypriot administration continue to support a bi-communal, bi-zonal federation.
