Sexy performances on shows such as The X Factor will be outlawed by further restrictions to pre-watershed TV.
The TV censor Ofcom will issue new censorship rule to apply to autumn schedules.
The move follows a Government report on the sexualisation of children and nutter protests.
An Ofcom spokesman said: The guidelines will be there to make sure that broadcasters like ITV don’t hover near the boundaries of harmful content to children. This is what happened with Rihanna’s performance on the show last year, where the broadcasting code was almost breached.
