An independent report on the sexualisation of childhood is to call for explicit adverts to be banned from areas near schools. Retailers are also to be urged to stop selling provocative clothing aimed at pre-teens.
The Conservative MP Nadine Dorries, who put forward a Private Member's Bill about teaching abstinence in sex education lessons, told Today presenter John Humphrys that "The problem is that we have the highest rate of teenage pregnancies in the UK, the highest rate of abortion.
"We have an over-sexualisation of this culture which is everywhere. It is in Sky Television, in video games that children now can access, on computer games, mobile phones.
"It's on billboard advertising, it's in teenage magazines, it's everywhere and it is too much. And we have to now say, enough."
Broadcasting executive Stephen Price, who has been a primetime scheduler for both the BBC and ITV, said that British television was "heavily-regulated industry".
But he agreed that the 9pm TV watershed "has kind of been diluted" by the advent of digital video recording which allows viewers to watch programmes at any hour of the day.
The review was commissioned by the government, carried out by the chief executive of the Mothers' Union, Reg Bailey, and will be published on Monday.
