The BBC Children's director has said she is "proud" of a sex change programme for children as young as six, which follows the story of a fictional transgender schoolboy who takes sex-change drugs.

Alice Webb said part of the BBC's "public service role" was to "stimulate conversation" and that the show Just A Girl had conveyed it's content in an "age appropriate way".

She made the comments after peers on the House of Lords Communications Committee questioned how programmers made the judgment on what age they thought it was appropriate to explore such a "difficult area".
