The amendments by Lord Stallard, a Labour peer, could give parents the right to withdraw children from lessons which involve sex education.
The BMA said it believes 'all children have a right to a comprehensive education of which sex education forms a necessary part. It can help young people to avoid sexual abuse and exploitation, unwanted pregnancies, sexually transmitted infections including HIV/Aids, and emotional distress arising from premature and ill-judged sexual experimentation . . (and) supports existing legislation which requires that all sex education be taught so as to encourage pupils to have due regard to moral considerations and the value of family life'.
