Porn: Parents 'should talk to children'

In an age when "extremely violent and sadistic imagery is two clicks away", school sex education is struggling to keep pace, a study suggests.

Relationship and sex education should be compulsory in all schools and include time for pupils to discuss the impact of pornography say the authors.

Sue Berelowitz, deputy children's commissioner for England, told the Today programme's Justin Webb that "children need good relationships and sex education in schools because not all parents feel able to talk to children about this stuff."

Schools "should be preparing children to be alert to this stuff", she added.

The BBC's social affairs correspondent Michael Buchanan reports.

First broadcast on the Today programme on Friday 24 May.
