PSC remains the leading party in Barcelona in the latest municipal barometer, but ERC has narrowed the gap sharply, according to results published on Friday as the city moves to within a year of the next local elections.

The survey, published by the Ajuntament de Barcelona, Barcelona City Council, puts the Socialists on 13% direct voting intention and ERC on 11.1%. For residents, party supporters and campaign teams, the result points to a much tighter contest for city hall than in the previous barometer wave.

Barcelona City Council’s earlier published barometer results for the first wave of 2025 had placed PSC on 16.1% direct voting intention and ERC on 7.5%. That means PSC is lower than in that wave, while ERC has gained ground markedly.

According to the survey, the elections in the Catalan capital would be a duel between the current mayor, Jaume Collboni, and the leader of Esquerra in the council, Elisenda Alamany.

Shift from the previous published barometer

The clearest documented comparison available in the published City Council material is with the first wave of 2025, when direct voting intention stood at:

  • PSC: 16.1%
  • Barcelona en Comú: 7.9%
  • ERC: 7.5%
  • Trias per BCN-Junts: 4%
  • CUP: 2.7%
  • PP: 2.4%
  • Vox: 1.9%

Against that published baseline, the new figures cited on Friday show ERC moving up from 7.5% to 11.1%, while PSC stands at 13%. The source material provided for Friday’s report does not include the full methodological table for the new wave, so no wider ranking beyond those headline figures is reported here from the official source alone.

What readers can check

Residents who want to review the City Council’s published barometer material can check the official Info Barcelona page, How do people rate the city?, which includes the first-wave 2025 results.

That official publication is useful for readers comparing how support has changed between waves, particularly for PSC and ERC, ahead of the next municipal election campaign in Barcelona.
