Interestingly...
In the original reporting of this...
"The Crown Prosecution Service told the defence it would oppose any attempt to inform the jury of the GMC investigation, on the basis that the allegations had not reached a final adjudication"
"Ultimately the GMC investigation was never concluded, because Hindmarsh removed himself from the GMC register, a process known as “voluntary erasure”. That effectively ended the investigation, and there was no regulatory finding against him"
Now the story has changed...
"Cheshire police and CPS say they were not told about inquiry into Prof Peter Hindmarsh before he gave evidence at nurse’s trial"
