Dr Gail Gilmartin, a senior medical advisor at the UK-wide MDDUS, said: ‘Whenever a doctor is considering whistleblowing they need to remind themselves about objectivity, evidence, issues of consent and confidentiality, and using proper process.

‘Most doctors are aware of the risks involved but we would urge members to seek our advice if they find they are contemplating such action.'

Lindsey McGregor, MDDUS solicitor, said: ‘Speaking out on patient safety issues, systems or on a colleague's conduct will be a matter of individual conscience but at all times GMC guidance must be at the forefront of your mind.

‘It is important to have read the guidance before embarking on this path and you should be prepared to be able to justify your concerns to others at all times.'
