More of French PM's interview with Mediapart: the TSCG, making EU more democratic, cabinet splits and Muslim anger
In this second and final part of his exclusive interview with Mediapart, French Prime Minister Jean-Marc Ayrault answers the suggestion that he is railroading the democratic process with the adoption of the European Treaty on Stability, Cooperation and Governance (TSCG), sets out his position on the widespread use of tax havens by big banks and corporations, and for greater representation of national parliaments in EU decision-making.
