The term E10 designates the ten non-permanent, elected members of the United Nations Security Council, distinguished from the P5 (the five permanent members holding the veto under UN Charter Article 27(3)). The institutional basis lies in Charter Article 23, which originally provided for six elected members and was amended in 1965 (entering into force 31 August 1965) to expand the elected contingent to ten, distributed across regional groups: five from Africa and Asia-Pacific, one from Eastern Europe, two from Latin America and the Caribbean (GRULAC), and two from Western European and Others (WEOG). Elected members serve two-year, non-consecutive terms under General Assembly Resolution 1991 (XVIII) of 1963, with five seats rotating each year through plenary elections requiring a two-thirds majority. The 1946 "gentlemen's agreement" within the Arab League and similar regional arrangements often pre-designate candidates, though contested elections — Saudi Arabia's 2013 rejection of its won seat, or the 2016 Italy-Netherlands split term — periodically disrupt orderly succession.
Procedurally, E10 coordination operates through several layered mechanisms. Each month, the Council presidency rotates alphabetically (English spelling) among all fifteen members, giving each elected state one presidency per two-year term during which it sets the programme of work, chairs consultations, and convenes signature events. Elected members chair the Council's subsidiary bodies — the sanctions committees, the Counter-Terrorism Committee (CTC), the 1540 Committee on non-proliferation, and working groups — assignments negotiated in December for the following year through the "Note 507" process formalized in document S/2017/507. Penholdership on country files, by contrast, has historically been concentrated among the P3 (United States, United Kingdom, France), a practice E10 members have repeatedly contested, demanding co-penholder arrangements on dossiers such as Yemen, Mali, and Colombia.
Beyond formal roles, E10 dynamics manifest in caucusing practices. Elected members convene monthly E10 coordination breakfasts, a practice institutionalized around 2018 under successive elected-member initiatives, to align positions on procedural questions, working methods, and humanitarian files. Joint statements, joint penholding (Kuwait-Sweden on the 2018 Yemen humanitarian resolution 2417), and joint draft resolutions allow elected members to shape outcomes despite lacking the veto. The Accountability, Coherence and Transparency (ACT) Group, launched in May 2013 and chaired by Liechtenstein, includes many E10 members and promotes the veto-restraint code of conduct on mass-atrocity situations. Cross-regional groupings such as the A3 (the three African members, coordinating through the African Union Peace and Security Council under the 2005 Ezulwini Consensus) and the L2 (the two Latin American members) constitute durable sub-caucuses.
Contemporary illustrations abound. During 2020–2021, the Tunisia-France co-penholdership produced Resolution 2532 on the COVID-19 ceasefire after weeks of E10-driven negotiation. The 2022–2023 term saw Albania, Brazil, Gabon, Ghana, and the United Arab Emirates form ad hoc coalitions on Ukraine-related procedural votes, with Mexico and Norway (2021–2022) jointly holding the humanitarian file on Afghanistan and Syria cross-border aid. Ireland and Norway's joint humanitarian penholdership on Syria (Resolution 2585 of July 2021) demonstrated how elected members can broker P5 compromises. The 2024–2025 composition — including Algeria, Guyana, the Republic of Korea, Sierra Leone, and Slovenia alongside continuing members — has continued the pattern of A3-plus configurations on African files, with Algiers and Freetown coordinating closely on Sahel matters with the AU Commission in Addis Ababa.
E10 dynamics must be distinguished from P5 dynamics, which center on veto management and great-power bargaining, and from Uniting for Consensus or General Assembly mechanisms such as the "Veto Initiative" (Resolution 76/262 of 26 April 2022) that operate outside the Council. The E10 are not a bloc in the ideological sense of the Non-Aligned Movement; their cohesion is procedural and situational rather than programmatic. Elected members lack the veto but exercise the "sixth vote" — the ability to deny the nine affirmative votes required under Article 27 for adoption — a leverage point used sparingly, as when Venezuela, Angola, and Malaysia abstained on key 2015 votes.
Controversies persist. The penholder system remains contested: a 2022 letter from several elected members to the Council president demanded systematic consultation before P3 drafts are tabled in blue. Capacity asymmetries disadvantage smaller elected states, which may field Council teams of three or four diplomats against P5 missions of twenty-plus. The "hidden veto" — P5 threats during consultations that suppress drafts before they reach the chamber — frustrates E10 initiatives, particularly on Israel-Palestine and Ukraine. Recent reform proposals under the Intergovernmental Negotiations (IGN) framework, including the L.69 Group and Common African Position (Ezulwini), would expand both permanent and elected categories, restructuring E10 arithmetic entirely.
For the practitioner, mastering E10 dynamics is indispensable. Desk officers preparing instructions for Council missions must map penholder configurations, anticipated A3 positions, and likely sub-caucus alignments before each vote. Campaigns for elected seats — typically launched five to fifteen years in advance through GA lobbying, hosted receptions, and reciprocal voting commitments — require sustained ministerial investment. Once elected, a state's two-year tenure offers a rare platform to shape global security agenda items, chair sanctions regimes affecting bilateral interests, and accumulate diplomatic capital that outlasts the term itself.
Example
In July 2021, Ireland and Norway, as E10 humanitarian co-penholders, brokered Resolution 2585 renewing the Bab al-Hawa cross-border aid mechanism into Syria after intensive negotiations with Russia and the United States.
