In order to ensure coherence and effective complementarity in the implementation of this Regulation and of other sectoral regulations applicable to gatekeepers, the Commission should benefit from the expertise of a dedicated high-level group. It should be possible for that high-level group to also assist the Commission by means of advice, expertise and recommendations, when relevant, in general matters relating to the implementation or enforcement of this Regulation. The high-level group should be composed of the relevant European bodies and networks, and its composition should ensure a high level of expertise and a geographical balance. The members of the high-level group should regularly report to the bodies and networks they represent regarding the tasks performed in the context of the group, and consult them in that regard.
