On 7/8 March 2013 the OPAL conference on ‘National Parliaments in the EU: The performance of Multilevel Democracy in Europe’ took place in Berlin. The conference was co-organised by the Jean Monnet Chair and the Arbeitskreis Europäische Integration as part of the OPAL project (Observatory of Parliaments after the Lisbon Treaty; http://opal-europe.org/). It received financial support from the European Commission and the Deutsche Forschungsgemeinschaft. The aim of the two-day conference was to bring together academics and practitioners from various backgrounds across Europe to discuss challenges and changes of parliamentary democracy in Europe. More than 75 participants from all over Europe attended the conference. Some contributions will form part of a forthcoming special issue in Western European Politics and the Palgrave Handbook on National Parliaments were presented. A detailed conference report will soon be published on our website. Please find more information here.
