Badenoch defended her record, telling MPs she had helped commission the Cass review into gender identity services for young people, and blocked the Gender Recognition Reform Bill in Scotland.

Last year a review by paediatrician Dr Hilary Cass found a lack of evidence around treatment for under-18s with the drugs.
