The PES Group in the European Committee of the Regions (CoR) brings together social democratic and progressive locally and regionally elected politicians from across the EU. The group aims at taking forward a progressive European vision with solidarity as well as social and territorial cohesion at its core.

The CoR is the EU's assembly of local and regional representatives. Its purpose is to involve presidents of regions, mayors, regional and local councillors in EU policy-making, and thus to give a voice to the European territories, which are directly responsible for the implementation of around 70% of EU legislation.

The PES Group works to achieve its political priorities through its work in all six thematic commissions of the European Committee of the Regions, covering a broad range of policy areas relevant to local and regional authorities. These commissions produce political recommendations on proposed EU strategies and legislation, as well as on issues identified by the Committee as being of key importance to Europe's cities and regions.

The PES Group organises meetings and citizens debates in cities and regions across Europe, bringing policymakers together and connecting them directly with the lived experience of Europe's citizens. The Group also hosts workshops, seminars and cultural events to encourage debate and drive political action on some of the most important issues facing Europe's citizens.
