Peter Hitchens: Sex education causes teenage pregnancy
Mail on Sunday columnist Peter Hitchens was booed by the Question Time audience when he said Britain had become a post-Lady Chatterley society where sex was "treated like tennis".
He also claimed sex education was causing teenage pregnancies and sexually transmitted diseases.
Mr Hitchens had been asked about a report by the Mother's Union earlier this week which expressed concern about the sexualisation of young children.
