Ofcom have given permission to the 4Digital Group to delay its launch til as late as next year.
The original timetable should have seen the new multiplex launch with eight services this Summer, but this will now depend on negotiations between the group and new GCap chief executive Ashley Tabor.
An Ofcom spokesman told Mediaweek: "Ofcom has allowed 4 Digital Group to delay the launch of its national radio multiplex licence beyond the original July 2008 launch date. However, Ofcom has not yet agreed a revised launch date and has asked 4Digital Group to provide updated plans, including new timings, by the end of the summer for Ofcom's approval."
A Channel 4 spokesman said: "We are not in a position to make any announcements at this stage."
According to Mediaweek, the new launch timetable depends on the outcome of discussions between newly installed GCap Media chief executive, Ashley Tabor, and 4Digital Group chairman, Nathalie Schwarz.
