Commercial Radio will set up a temporary studio in Victoria Park for a live broadcast of the July 1 protest. Five commentators will report from the scene and interview celebrities taking part in the march, programme adviser Leung Man-tao said yesterday. 'We do not have a political affiliation, nor a position on the march. But we do have some basic values,' Mr Leung said. 'As the march is an issue with enormous public interest, Commercial Radio is obliged to properly use the airwaves to inform the public about what's happening there. It is a kind of public service.' Mr Leung said Commercial Radio could help avoid a repeat of some of the confusion seen at last year's demonstration, by broadcasting information on transport and police arrangements. It will run a six-hour live broadcast from 2pm to 8pm. Rival broadcaster RTHK says it is not making any special arrangements for July 1.
