The broadcasting standards watchdog has fined the Tehran-backed channel, Press TV, £100,000 for multiple breaches of its code.
In October it emerged that Ofcom was considering imposing sanctions in Press TV following the broadcast of an interview with jailed Newsweek journalist Maziar Bahari in July 2009. A subsequent investigation found that the programme breached its standards on fairness and privacy.
Mr Bahari later said that the interview, in which he spoke about covering the Iran election protests, was a forced, scripted confession, under threat of execution.
In the ruling, Ofcom said the hefty fine had been imposed because of "the seriousness of the breaches".
