The World: Washington - NAB wants brakes put on XM and Sirius merger

The head of the National Association of Broadcasters has called for the proposed $13 billion merger of the satellite radio services Sirius and XM to be abandoned.

David Rehr, the NAB chief executive, claims that any gains will go mainly to Wall Street and the companies' executives, rather than consumers.

The merger would halt the rivalry between Sirius and XM for presenters and subscribers, but has been criticised as anti-competitive.

Rehr has accused Mel Karmazin, the Sirius chief executive, of using the merger to cover up poor business decisions. Karmazin claimed the NAB was bankrolling studies purporting to show why the merger would be bad.
