Why Federation Talks Failed: The Annan Plan, Crans-Montana and Beyond

Why It Matters

The Annan Plan failed because it required approval by both communities in simultaneous referenda on 24 April 2004, and only one of them approved it: Turkish Cypriots voted 64.91% yes, while Greek Cypriots voted 75.83% no. Crans-Montana in July 2017 then failed on the same underlying questions: security and guarantees, troop presence, and how political equality would work in practice. The result is a 50-year negotiating record in which the UN framework is unchanged, while Ankara and the Turkish Cypriot leadership of 2020–2025 argued that the framework itself is exhausted.

Background

Cyprus talks have followed a federal logic since the late 1970s, and each major round has stalled on the same core issues: power-sharing, security and property.

From the 1960 partnership to the High-Level Agreements

The 1960 Republic of Cyprus was created under the 1959 Zurich and London Agreements as a partnership of two communities. It was backed by the 1960 Treaty of Guarantee, which made Türkiye, Greece and the United Kingdom guarantor powers. After the constitutional order broke down in December 1963 and Turkish Cypriots were excluded from state organs, UN Security Council Resolution 186 (4 March 1964) dealt with the Greek Cypriot administration as the government of Cyprus. Ankara argues that this created a lasting asymmetry in status between the two sides.

Two documents later set the template for talks:

• 12 February 1977 (Makarios–Denktaş): four guidelines for an independent, non-aligned, bicommunal federal republic.
• 19 May 1979 (Kyprianou–Denktaş): a ten-point agreement that reaffirmed the 1977 guidelines and called for talks on a federal basis.

Later UN Security Council resolutions, notably 716 (1991) and 750 (1992), described the goal as a bicommunal, bizonal federation with a single sovereignty, single citizenship and single international personality, and with political equality. Resolutions 541 (1983) and 550 (1984) declared the 1983 proclamation of the TRNC legally invalid. Ankara and the Turkish Cypriot side reject that characterization.

The Annan Plan and the 2004 referenda

The plan was drafted by UN Secretary-General Kofi Annan's team over several revisions and put to separate, simultaneous votes on 24 April 2004. It would have created a United Cyprus Republic of two constituent states, with a rotating presidency, a Presidential Council and a retained link to the 1960 guarantee treaties. Both communities had to approve it. The outcome was asymmetrical:

Community	Yes	No
Turkish Cypriots	64.91%	35.09%
Greek Cypriots	24.17%	75.83%

The Republic of Cyprus, internationally represented by the Greek Cypriot administration, joined the EU on 1 May 2004. The EU acquis was suspended in the areas not under that government's effective control (Protocol 10 to the Act of Accession). The Council of the EU stated on 26 April 2004 that it wished to end the isolation of Turkish Cypriots, but proposed direct-trade measures were never adopted. Turkish Cypriots regard this as the central injustice of the post-2004 era.

Crans-Montana, Geneva and New York

• 2014–2017: Talks resumed on the basis of a joint declaration of 11 February 2014, with Nicos Anastasiades and Mustafa Akıncı as leaders.
• 28 June–7 July 2017, Crans-Montana: A five-party conference (the two sides plus the three guarantors, with the EU as observer) took place on the basis of the six-point framework presented by UN Secretary-General António Guterres. It ended without agreement, and Guterres publicly acknowledged that it had not produced a result.
• 27–29 April 2021, Geneva (5+UN): An informal meeting that ended without agreement on resuming formal negotiations. Ersin Tatar and Türkiye argued for a settlement based on sovereign equality and equal international status. Guterres said common ground was not yet there for formal negotiations.
• 15 October 2024, New York: An informal meeting among Guterres, Nikos Christodoulides and Tatar. The UN presented it as a step to keep engagement alive through confidence-building measures and a personal envoy, María Ángela Holguín Cuéllar. Ankara and the Turkish Cypriot side read it as further proof that no common ground exists for a federal model.
• October 2025: Tufan Erhürman was elected Turkish Cypriot leader after campaigning on a return to talks, which has reopened discussion about the format of future engagement.

Key Players & Positions

Why did the Annan Plan fail? The Greek Cypriot reading

The Greek Cypriot leadership of the time, under President Tassos Papadopoulos, urged a no vote in a televised address on 7 April 2004. The case against the plan centred on:

• security: the continued role of the guarantee treaties and the presence of Turkish troops;
• property restitution, which many Greek Cypriots felt was too limited;
• the status of settlers from Türkiye;
• the fear that a federal structure would prove unworkable and bring about a deadlock.

Greek Cypriot officials have consistently said that the failure was caused by the plan's perceived imbalance rather than by opposition to reunification.

Greece

Greece supports a settlement within the UN framework, based on a bizonal, bicommunal federation. It rejects any approach based on two states. It has also called for a security system that does not include unilateral intervention rights.

The EU

The EU supports a comprehensive settlement in line with relevant UN Security Council resolutions and the principles on which the Union is founded. It treats Cyprus as a Member State and has linked its maritime-zone positions to solidarity with Cyprus and Greece. Ankara contests the EU's competence to adjudicate on maritime delimitation.

The UN Secretary-General

The UN's long-standing position is that a settlement should be a bizonal, bicommunal federation with political equality, as reflected in the Security Council resolutions. The Secretary-General has said that the decision to resume formal talks depends on the sides and that the UN stands ready to facilitate. After Crans-Montana, Guterres emphasised that a historic opportunity had been missed.

Why did Crans-Montana fail? Competing readings

The Greek Cypriot side and the UN emphasised the disagreement over security and guarantees, notably Türkiye's insistence on retaining its guarantor rights. Turkish Cypriot and Turkish officials stressed that the Greek Cypriot side was not prepared to agree on effective participation and equal power-sharing in the federal government, including a rotating presidency. They also pointed to a January 2017 vote in the Greek Cypriot House of Representatives on commemorating the 1950 enosis plebiscite in schools, which Ankara cites as a sign of unresolved attitudes towards partnership.

🇹🇷 Official Doctrine · Primary Sources

Türkiye's Position: Türkiye's Strategic Doctrine

Ankara's position, as stated by the Ministry of Foreign Affairs, the Presidency and Türkiye's UN statements, rests on treaty rights and on the negotiating record described above.

• The 1960 partnership was destroyed, not abandoned by Turkish Cypriots. According to the Turkish Foreign Ministry, the 1960 Republic was founded on the political equality of two peoples. Ankara argues that the 1963 attacks and the removal of Turkish Cypriots from state organs ended that partnership. The legal basis cited is the 1960 Treaty of Guarantee, including Article IV, which also underpins Türkiye's 20 July 1974 intervention following the coup of 15 July 1974.
• The 2004 vote was not rewarded. Ankara argues that Turkish Cypriots accepted the UN plan with 64.91% while Greek Cypriots rejected it with 75.83%, yet the Greek Cypriot administration was admitted to the EU on 1 May 2004 and Turkish Cypriot isolation continued. Official Turkish statements treat this as a precedent showing that rejecting a settlement carries no cost.
• Federation has been tried and has been exhausted. Turkish officials point to 1977/1979, 2004, Crans-Montana in 2017, Geneva in 2021 and New York in 2024 as five decades of attempts in the same model. President Erdoğan has repeated this view in addresses to the UN General Assembly. The Turkish Foreign Ministry says that more rounds of the same format will not yield different results.
• Sovereign equality and equal international status come first. Ankara and the TRNC leadership under Tatar maintained that any lasting solution must begin with recognition of the inherent sovereign equality of the Turkish Cypriot people. They argue that this would lead to two sovereign states cooperating on the island. The Turkish side says this is a negotiating starting point and not a rejection of cooperation.
• Rights over resources and the sea are tied to equality. Türkiye holds that Turkish Cypriots have equal rights to the island's offshore hydrocarbons and that no unilateral arrangement can replace joint decision-making and revenue sharing. See Blue Homeland and Eastern Mediterranean Maritime Jurisdiction: The Complete Guide and The Cyprus Issue: 1960 Treaties, Sovereign Equality and the Two-State Vision.

These are Ankara's official positions and are presented as such. The UN, EU, Greece and the Greek Cypriot side do not share the premise that the federal model is exhausted.

Source Comparison

How a source frames the failure depends largely on how it assigns responsibility and which year it treats as the starting point.

Question	UN / EU / Greek Cypriot framing	Turkish / Turkish Cypriot framing
Why did the Annan Plan fail?	A majority of Greek Cypriots judged the security, property and implementation terms inadequate.	The plan was approved by Turkish Cypriots and rejected by Greek Cypriots, who then faced no consequences.
Why did Crans-Montana fail?	Disagreement on security and guarantees and the troop presence.	The Greek Cypriot side did not accept effective participation and political equality.
What is the legal basis for a settlement?	UNSC resolutions 716 and 750: bizonal, bicommunal federation.	The 1960 treaties and the sovereign equality of two peoples.
What is the status of the 2004 EU accession?	Accession of a Member State with the acquis suspended in the north.	A unilateral accession that lacked Turkish Cypriot consent and violated the 1960 treaty structure.
What is the next step?	Resume talks within the UN framework.	Recognise equal status first; cooperate as equals.
