Dr Hilary Cass: How world-renowned paediatrician behind damning review of NHS ... trends now
She's undeniably one of the most influential paediatricians of her generation and, perhaps most importantly, is no stranger to raising the alarm about patient safety concerns.
So it's no wonder that Dr Hilary Cass was tasked with overhauling care for gender-questioning children in the UK.
Appointed by NHS bosses in the wake of the Tavistock scandal, Dr Cass has sorted fact from fiction in a debate which has become exceptionally toxic.
Her damning review of gender identity services for young people spans nearly 400 pages and has been close to four years in the making.

It says children have been let down by a lack of research and evidence on medical interventions, specifically puberty blockers and hormone drugs.
Guidelines themselves aren't evidence-based, she ruled.

Dr Cass, in her 60s, is no stranger in raising concerns to those in power.
In 2013 it was revealed she left Great Ormond Street Hospital after raising concerns about patient safety.
She warned bosses that inadequate staffing, poor morale and a lack of co-operation between departments was putting patients at risk.
After emailing managers an account of her concerns, GOSH used a confidentiality agreement to settle a long-running dispute with her which saw her demoted and led to her departure.
It sparked a national conversation about the use of so-called 'gagging clauses' in the NHS.
