Brass Eye has again been rapped by TV watchdogs - this time for a trailer.

The Broadcasting Standards Commission has criticised Channel 4 over a advert after three viewers complained that it appeared to condone paedophilia.

Channel 4 said the advert, like Chris Morris's show, intended to highlight media treatment of the issue.

But the Commission has ruled: "The brevity of the trailer would have made it difficult for the audience to sense it was a satire or that it was promoting a satirical programme.

"It was too subtle and too refined for this to be easily understood."

Channel 4 has already had to apologies about the original programme, aired in July, after watchdogs criticised the show for causing distress.

However, the station does play to repeat the episode in the future.
