The European Commission has launched a formal infringement procedure against Bulgaria for the reported lack of effectiveness of its national telecoms regulator. The regulator delayed appointing a chairperson and failed to undertake core tasks under existing telecoms rules, such as conducting market analyses. In addition, the board of the incumbent telecoms operator included the chairperson of another authority with certain regulatory powers, causing a conflict of interest that may jeopardise the independence of the regulator, a key element for ensuring effective implementation of the EU Telecoms Rules. As meetings with the Bulgarian authorities and letters from the Commission have failed to resolve these problems, the Commission considers that Bulgaria has failed to uphold its obligations under EU law.
