Having approached him for Celebrity Big Brother and then decided against including him, Channel 4 still seems determined to give the controversial historian David Irving, once imprisoned in Austria for Holocaust denial, plenty of airtime.

On Tuesday night, C4's offshoot channel, More4, is showing a 90-minute documentary, An Independent Mind, in celebration of the 60th anniversary of the Universal Declaration of Human Rights.

It is publicising it heavily, with a special screening the night before at the Royal Society of Arts, hosted by Channel 4 News's foreign correspondent Jonathan Miller. According to the puff: 'This unique film gives a voice to eight characters from around the world who have fought to exercise their right to free speech.'

What C4 doesn't say is that the film's eighth and final hero is Irving. The timing is fortunate for Irving, if not for the rest of us, since he's currently trying to flog his self-published misery memoir.

The Board of Deputies of British Jews tells me the programme should not be shown. 'Whatever airtime David Irving gets is too much,' says chief executive Jon Benjamin. 'Here, he once again seems to be casting himself in the role of victim.'
