A BBC chief insists she is 'proud' of the controversial programme targeting children as young as six about a schoolboy who takes sex-change drugs. Children's director Alice Webb defended Just A Girl after parents reacted angrily to the CBBC show, which depicts an 11-year-old's struggle to get hormones that stunt puberty, making it easier to have sex-change surgery in the future. Concerned campaigners said it could 'sow the seeds of confusion' in young minds. But Ms Webb said the BBC has a duty 'to make sure that we are stimulating conversation'.
