DJ: Can I ask you about a different but related problem, wearing your hat as Channel 4 Chairman. Last year there was a very remarkable Dispatches documentary Undercover Mosque. The worrying thing about that case was partly what they discovered was going on in the mosques, the preaching of extremist views. But even more worrying in some ways was that the police investigated, but instead of attempting to bring prosecutions against some of these extremists, who were quite clearly breaking the law, they decided instead to turn on Channel 4, and condemn them...

LJ: They made a formal complaint to Ofcom, the regulator.

DJ: Exactly; which was ultimately rejected wasn't it?

LJ: Absolutely. We and the production company sued them for libel, and they settled and apologised.

DJ: But are you confident that this was a one-off case where some bad decisions were made - not necessarily at the highest level? They did fight the case all the way through. Are you worried that this implies some elements of the authorities would simply rather not know what might be happening in mosques, and that their instinctive reaction is to shoot the messenger, when all you were doing was an ordinary bit of investigative journalism?

LJ: Well, I think the overall outcome was very satisfactory. West Midlands Police were found to have behaved very badly indeed, and the media covered it extensively, with a great deal of editorial comment saying it is absolutely not the role of the police to attack legitimate reporting of extremists' behaviour. I think they and other government bodies will think very hard indeed about taking a similar tack again.
