Following the decision by the Office of Fair Trading to refer the merger between National Grid Wireless and Macquarie to the Competition Commission (CC) on 8 August 2007, the CC has published an issues statement setting out the main areas of its investigation. These include: defining the relevant market; whether terrestrial broadcasting should be distinguished from digital broadcasting; and whether national and regional broadcasts should be regarded as separate markets. The CC will decide whether, and to what extent, the merger would produce anti-competitive effects.
