LONDON: The UK's biggest commercial broadcaster, ITV, has shut down its interactive digital channel, ITV Play, pending an audit of its telephone systems.

The review, by accountants Deloitte, was prompted by a furore over a quiz on a rival channel's talkshow where would-be contestants were encouraged to phone-in despite the fact that the winners had already been chosen.

An ITV spokesman insisted: "We believe all of our programmes are [call-in] compliant but we have to carry out the review nonetheless."

Meantime, Britain's premium rate calls regulator ICSTIS will meet with broadcasters and programme makers on Thursday to discuss the current controversy about viewer-participation TV.
