The Regional Council of Alsace (Conseil régional d'Alsace) is composed of 37 councillors, elected by proportional representation in a two-round system. The winning list in the second round is automatically entitled to a quarter of the seats. The remainder of the seats are allocated through proportional representation with a 5% threshold.
In the 2007 legislative election, thirteen out of the sixteen Alsatian deputies were from the UMP, one was from the opposition PS, and one was from the UMP's coalition partner, the New Centre. One deputy, Éric Straumann, was a UMP dissident.[1]
