Mr Cameron is also set to endorse age-rated certificates for pop videos, and the banning of certain advertising billboards near schools, after the publication of a Government commissioned review on the sexualisation of youngsters.
The Mothers' Union Chief Executive Reg Bailey, who published the review yesterday, said that TV regulator Ofcom needs to rewrite the broadcasting code to prevent raunchy performances before the watershed. This would mean that controversial artists like Rihanna would only have their music videos played after a certain time, and would be subjected to cinema-style age ratings.
Measures are also to be put in place to restrict the sale of inappropriate clothing and logoed goods to children.
Mr Cameron also supports moves to block adult content on mobile phones, and is to hold talks with retailers, advertisers, broadcasters, magazine editors, video games and music industry chiefs later in the year to discuss progress of the moves.
