There is a long standing debate on the reform of the EU budget. According to the final agreement on the Multiannual Financial Framework (MFF) 2014-2020 signed in December 2013, the Commission will present, by the end of 2016 at the latest, a review of the functioning of the MFF. The review will be accompanied by a legislative proposal for the revision of the MFF 2014-2020. This revision could provide an important occasion and stimulus to reform the financing of the budget and to readjust the spending structure.
