PES Group - European Committee of the Regions (CoR) is a political group that 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 the EU legislation.
