LONDON, Jan 20: British authorities on Friday revoked the licence of Press TV, the Iranian state broadcaster's English-language outlet, saying the channel had breached a string of regulations.

The network hit back on its website, calling the decision 'a clear act of censorship' Ofcom, Britain's independent broadcasting watchdog, said in a statement that Press TV failed to obey a rule that its licence should be held by its Tehran headquarters, instead of by its London office as is currently the case.

Press TV had also 'indicated it is unwilling and unable' to pay a fine of pound 100,000 ($156,000) imposed in December for showing an interview in 2009 with an imprisoned journalist for a US magazine, Ofcom said.

The Ofcom statement said that under its broadcasting rules, all licence holders in this case Press TV's office in London must have general editorial control of the channel.

But the watchdog said it was apparent that 'editorial control of the channel rested with Press TV International' in Tehran, and that Press TV had ignored a 35-day deadline to transfer the licence there.

In December, Ofcom said Press TV had also invaded the privacy of Newsweek journalist Maziar Bahari by filming an interview without his consent while he was in detention during protests in Iran in 2009.

It also ruled that its treatment of him was biased.—AFP
