LONDON: UK commercial radio companies have blasted the government for not setting a firm date for the medium's analogue signal switch-off.

Industry body Radio Centre says automakers, retailers and digital radio set producers need "regulatory certainty and clarity" if serious investment is to continue.

Argues Radio Centre ceo Andrew Harrison: "With around a quarter of people listening to the radio in their cars, motor manufacturers are key to the future of digital radio."

But most carmakers are unlikely to put digital radios into their vehicles as standard until the government decides on the switchover date for a digital-only service. The changeover for television will be complete by the beginning of 2012.
