After a number of failed attempts to introduce mandatory transparency regulations for the EU institutions, the European Commission (EC), the European Parliament and the Council of the EU have started a fresh round of negotiations. The aim is to strengthen the EU Transparency Register by making certain types of interactions with their respective institutions conditional on registration by the interest representatives. The current round of negotiations between the EU bodies is based on the EC’s 2016 proposal to make the Register used jointly by the EC and EP obligatory and include the Council.
