There's a "clear and obvious" way out for the PL which preserves the brand and makes them look decent regulators.
"Following the release of 6 or 7 edited emails out of over 3 million illegally obtained emails by a.hacker, there were legitimate concerns raised by PL members about how City were behaving.
We have spent a long time investigating these concerns and have raised them with City. As a result we can confirm that there are no issues, nothing untoward has been done and all rules have been followed. City have co-operated fully in our investigation, which will go no further, and we thank them for that co-operation."
Etc, etc "needed to check, very thorough investigation", etc
