From the document above:
A formal GMC fitness to practise referral was made on 2 November 2018 by Dr Richard Cooper, Director of Medical Trainee Revalidation at HEE NE. This followed the GMC notifying Dr Harrop’s employers of posting tweets in May 2018, following which Dr Cooper met with Dr Harrop to discuss the concerns raised. The HEE NE Revalidation Team then received a number of further complaints about Dr Harrop’s posts on Twitter. The complaints were from a variety of individuals and in various forms such as via email, letters and tweets. The HEE NE were concerned with regards to the style and tone of some of the tweets that individuals may have felt that Dr Harrop was being aggressive, or believed that they were being bullied. This resulted in a further meeting being conducted with Dr Harrop.
5. In his referral to the GMC, Dr Cooper stated that if any individuals who read Dr Harrop’s tweets happened to come into contact with him in a clinical setting, they might feel they could not trust Dr Harrop if they had divergent views to his in the transgender rights debate. Dr Cooper indicated that HEE NE believed that Dr Harrop was not following the GMC Guidance `Doctors use of Social Media' April 2013 (‘Social Media Guidance’) particularly in respect of the areas: Respect for colleagues, Anonymity, Communication, Partnership and Teamwork, Establish and maintain partnerships with patients, Maintaining trust, Show respect for patients, Treat patients and colleagues fairly and without discrimination, Act with honesty and integrity.
So, Dr Richard Cooper, as Director of Medical Trainee Revalidation at HEE NE, voicing concerns regarding Harrop ignoring warnings over his SM use and his ability to build trust with patients with a differing viewpoint, which lead to Dr Cooper referring Harrop for a formal fitness to practice review.
That doesn’t sound like a ringing endorsement for Harrop.
