The European Parliament adopted 7 amendments, and the Commission can accept all of them in full. In particular, Parliament introduced new text to highlight the need for monitoring by regulatory authorities and/or the Commission, with regulatory action to be taken where appropriate on a number of key issues. Those concern in particular the interoperability of services for end users, charges which contribute to tariffs for end users, the need for market analysis on international roaming, and possible adverse effects of new infrastructure on the environment and the landscape. The Commission can accept these amendments since they clarify the regulatory supervision powers included in the relevant provisions of the Council's common position.�
