# Catalonia 2027 municipal election developments – August 2026 > Live situation record from CLSTR: https://clstr.news/situations/catalonias-2027-municipal-elections-confront-candidate-gaps-and-high-mayoral-turnover > Updated: 2026-08-14T06:52:04.000Z. Sources: 45. Developments: 17. As the May 2027 municipal elections approach, Catalan political parties are actively forming alliances and selecting candidates. In Barcelona, Junts per Catalunya secured Jordi Martí as its mayoral candidate following an internal primary, where he defeated Pilar Calvo, Jaume Alonso‑Cuevillas, and Glòria Freixa. Martí, supported by former mayor Xavier Trias, has ruled out coalitions with Aliança Catalana. Meanwhile, Aliança Catalana has named historian Jordi Aragonès as its Barcelona candidate, running on a platform to address what it terms an “immigration‑driven” housing and security crisis. Aliança Catalana is experiencing significant growth, with polls projecting it could become the third-largest force in the Catalan Parliament with 23–25 seats. The party has also fielded candidates in Mont‑roig del Camp and Girona, though it faced setbacks in Figueres after withdrawing Arnau Liesa due to a personal scandal. In Cambrils, tension exists as Junts spokesperson Enric Daza announced his candidacy under the Aliança banner, a move contested by other local Junts councilors. Other parties are also mobilizing: the Social democrats (SDP) lead candidate Gerard Alís is seeking a broad left-wing coalition, while PP candidate Daniel Siera is campaigning on security and tax cuts. The independentist party Alhora has presented its first list in Sant Cugat del Vallès, and the CUP has opted for grassroots activism over running a list in Terrassa. In a recent development, pro-independence parties Junts, ERC, and CUP have proposed a municipal pact to ensure political stability. The framework includes automatic voting for the most-voted pro-independence list among the three to avoid deadlocks, a preference for coalition governments, and a strict “sanitary cordon” against parties associated with the application of Article 155, such as PSC, PP, Vox, and Aliança Catalana. ## Timeline ### 2026-08-14: Catalan pro-independence parties propose municipal pact Catalan pro-independence parties Junts, ERC, and CUP are being urged to adopt a municipal pact to ensure stable governments and prevent political blockages in future elections. 2 sources. https://clstr.news/cluster/catalan-pro-independence-parties-propose-municipal-pact ### 2026-08-10: Catalonia political parties form alliances for 2027 elections Catalan political groups are forming new alliances for the 2027 municipal elections, with Junts securing pacts in Mollerussa and Solsona while exploring further agreements in Balaguer. 2 sources. https://clstr.news/cluster/catalonia-political-parties-form-alliances-for-2027-elections ### 2026-07-27: Aliança Catalana surges to become Catalonia’s third force and fields mayoral candidate in Cambrils Aliança Catalana, led by Silvia Orriols, announced Enric Daza as its mayoral candidate in Cambrils as a poll shows the party poised to become Catalonia’s third force, overtaking Junts. 2 sources. https://clstr.news/cluster/aliana-catalana-surges-to-become-catalonias-third-force-and-fields-mayoral-candidate-in-cambrils ### 2026-07-16: Catalan Parties Alhora and CUP Shape 2027 Municipal Election Strategies Alhora launched its first 2027 municipal candidacy in Sant Cugat, focusing on housing and a potential independence referendum, while the CUP said it will not run in Terrassa, opting to strengthen its anti‑cap‑l 4 sources. https://clstr.news/cluster/catalan-parties-alhora-and-cup-shape-2027-municipal-election-strategies ### 2026-07-14: Cambrils Junts councilors split over move to Aliança Catalana Aliança Catalana aims to grow in Catalonia, but Junts councilors in Cambrils split over joining;
