The deal between the UK and the EU has not put an end to their talks. As negotiations will continue on a number of fronts, UK-EU parliamentary cooperation will be essential to ensure that citizens’ interests are taken into account. The EU-UK Trade and Cooperation Agreement (TCA) sets out that the European Parliament and the UK Parliament may establish a Parliamentary Partnership Assembly (PPA) that would provide a forum for exchanges of views. It is still unclear whether and when a PPA will be created. As the TCA suggests, its establishment appears to be voluntary and at the discretion of the legislatures from both sides. So far, the parliamentary dimension within the overarching governance of the TCA has remained at an embryonic stage, leaving many questions unanswered. Yet the PPA would not be the only channel for parliamentary cooperation and other formats could develop.
