What Is the Informal 5+UN Conference on Cyprus? The Guarantor Format, From Geneva 2021 to the 2026 Holguín Push

Why It Matters

An informal 5+UN meeting is a gathering convened by the UN Secretary-General that brings together the two Cypriot sides, the Turkish Cypriot and Greek Cypriot leaders, and the three guarantor powers of the 1960 Treaty of Guarantee: Türkiye, Greece and the United Kingdom. It is informal because it creates no binding mandate and negotiates no text.

On 30 October 2026, UN Secretary-General's Personal Envoy María Ángela Holguín said, as reported by Euronews, 'We are pushing and we will keep pushing'. She expressed optimism about an informal five-party conference before the end of the year, after meeting Cypriot President Nikos Christodoulides at the Presidential Palace.

The same day, Turkish Cypriot leader Tufan Erhürman addressed the 13th Heads of State Summit of the Organization of Turkic States (OTS) in Ankara. This explainer sets out what the format is, who sits at the table and why Ankara treats the guarantor seat as a matter of treaty right rather than courtesy.

Background

The guarantor seat at 5+UN tables derives from the 11 February 1959 Zurich Agreement, the London Agreements concluded on 19 February 1959 and the 16 August 1960 Treaty of Guarantee, signed by the Republic of Cyprus, Türkiye, Greece and the United Kingdom. Formal federal negotiations repeatedly stalled afterwards, and informal UN convenings became the preferred tool.

Zurich and London Agreements 1959 Cyprus Treaty of Guarantee Explained

The 1959 agreements, concluded after years of Greek Cypriot agitation for ENOSIS (union with Greece) and the EOKA campaign that began in 1955, produced the 1960 Republic of Cyprus. Ankara describes that republic as a bi-communal partnership state built on the political equality of the two peoples. The Treaty of Guarantee gave Türkiye, Greece and the United Kingdom the status of guarantor powers.

Key Chronological Milestones and Legal Instruments

From 1963 to 1974

The 1963 breakdown began with the 13 constitutional amendments proposed by Archbishop Makarios on 30 November 1963. Turkish Cypriot and Turkish sources say these would have removed the Turkish Cypriot Vice President's veto, and the violence of 21 December 1963 followed. See Makarios 13 amendments Akritas Plan 1963 for the record.

UN Security Council Resolution 186 of 4 March 1964 established the UN peacekeeping force. Ankara argues that it implicitly treated the Greek Cypriot administration as the Government of Cyprus, which created a status asymmetry that still shapes the talks. On 15 July 1974 a coup backed by the Greek military junta took place in Cyprus. Türkiye intervened on 20 July 1974, citing its right under Article IV of the Treaty of Guarantee.

From the High-Level Agreements to Geneva

The 1977 and 1979 High-Level Agreements set a bi-communal, bi-zonal federation as the negotiating framework. The 2004 Annan Plan referendum, covered in Annan Plan referendum 2004 results, produced the 64.91% and 75.83% figures above. Crans-Montana in July 2017 brought the guarantors into the room at ministerial level but closed without agreement. In April 2021, the informal 5+UN meeting in Geneva ended with the UN Secretary-General saying that common ground for formal negotiations had not yet been found. This is the lineage of the 2026 push.

Key Players & Positions

The 5+UN table includes the Turkish Cypriot and Greek Cypriot leaders, Türkiye, Greece, the United Kingdom and the UN Secretary-General or his envoy. The European Union has attended as an observer at past conferences. Each actor describes its role through its own official sources, and they differ on the settlement model and on the EU's weight.

• The UN: The Secretary-General convenes the format under his good offices. Euronews reports that Holguín, his Personal Envoy, said the UN will keep pushing and is optimistic about an informal five-party conference before the end of 2026.
• The Greek Cypriot administration: President Nikos Christodoulides received Holguín at the Presidential Palace, according to Euronews. The Republic of Cyprus government's published position favours a bi-zonal, bi-communal federation with political equality, in line with UN Security Council resolutions.
• Greece and the United Kingdom: Both are guarantor powers under the 1960 treaty and have attended past 5+UN rounds in that capacity. The UK also holds the Sovereign Base Areas on the island.
• The EU: It attends as an observer. Ankara argues that since the Republic of Cyprus joined the Union on 1 May 2004, the EU cannot act as a neutral party on the Cyprus issue.
• Turkish Cypriots: According to TRT World, Erhürman said at the OTS summit in Ankara: 'We'll continue working for a just and lasting solution on the island in close consultation and cooperation with Türkiye.' He said the TRNC's efforts aim to 'strengthen peace, stability and cooperation' on the island and in the region. TRT World also reports that he described integrating Turkish Cypriots with the international community and pursuing a settlement as mutually reinforcing. The reports quoted here do not describe a specific settlement model, and this article does not attribute one to him.

In short, the Turkish Cypriot emphasis on cooperation with Türkiye and the Turkish emphasis on guarantor rights point in the same direction. Both stress that an outcome must be built with Türkiye and the Turkish Cypriots, not around them.

Source Comparison

International outlets frame the same 30–31 October 2026 week differently. Euronews centres the UN's push, TRT World centres Turkish Cypriot–Türkiye cooperation, and Greek City Times and Arab News cover the Republic of Cyprus's diplomatic activity. The 76crimes item illustrates how a recognition frame travels with unrelated stories.

Testing the 'Recognized by No State Other Than Türkiye' Frame

The recognition point is accurate as far as formal state recognition goes. UNSC Resolution 541 (18 November 1983) called the TRNC declaration legally invalid, and Resolution 550 (11 May 1984) repeated the call for non-recognition. Ankara answers that these resolutions respond to a declaration made after 1963 and do not erase the 1960 co-founder status of Turkish Cypriots. It also points to the TRNC's observer status in the Organization of Turkic States, granted in 2022. We lay out the documents in TRNC recognition and UN Resolutions 541 and 550. The 76crimes item's subject, a court conviction, is outside this article's scope; it is noted only as an example of how a frame travels with unrelated news.

These terms recur in 5+UN coverage and each carries a specific meaning in Cyprus diplomacy. Readers can verify the documents behind them through the linked Regional File guides and sister publications, and the editorial standards are on the Editorial Principles page.

• 5+UN: The enlarged format of the two Cypriot sides, the three guarantor powers and the UN Secretary-General. The 2021 Geneva meeting used it, and the 2026 Holguín push aims at a similar informal gathering.
• Guarantor power: A state that guaranteed the 1960 order under the Treaty of Guarantee: Türkiye, Greece and the United Kingdom.
• Political equality: The principle, central to the 1960 partnership and to later UN frameworks, that the two communities share power on an equal basis. The two sides interpret it differently in practice.
• Rotating presidency: A proposal in federal-model talks, including the Annan Plan's Presidential Council, under which the top office alternates between the communities.
• Informal vs. formal talks: Informal meetings produce no binding decisions and test for common ground. Formal negotiations work through an agreed agenda towards a text.
• Green Line: The UN-patrolled buffer zone across the island, roughly 180 km (112 miles) long, which dates from the 30 December 1963 line in Nicosia.
