Adding on to what DavidJN wrote, in every instance I know of where a complaint is made about some supervisor's allegedly illegal behavior, if you can't present the body, the weapon, video recording of the crime, audio recording of a confession, clear demonstration of motive and opportunity, and several confirming statements from other witnesses, there will be little interest in the complaint. Most of what I have seen are discrimination complaints, but also a few corruption matters: in the one corruption matter I was personally involved with, after I told the perpetrator what was wrong with what she was doing along with, "DO NOT FUCKING DO THIS!" and she did it anyway, she swore to the investigators sent her way, that, gosh, she was unaware of all the conflicts of interest and the deviation from normal procedures ... and the investigators decided they didn't really have enough to make a solid case on. (Part of the problem was that I found another way to stop the crime, so it was easy to say that in the end there was no harm done.)
What I would suggest you look into, Sleepy Ted, is whether there is a deep-pocketed entity that lost money for being invested in one of the disfavored funds. That entity could bring a civil suit, where the standard of proof is "preponderance of evidence" rather than "beyond a reasonable doubt," which is ultimately the criminal standard if a complaint through agencies is made (this assumes American law, although probably English law is very similar). With your direction, that entity could request information -- first just as a matter of due diligence and then as a matter of discovery -- that would probably, based on what you have written, rise to a level of a winnable civil suit.
And of course the two downsides to this are (a) you don't get any whistleblower reward and (b) the investment manager will probably realize that someone inside is feeding information to the complainant, and will brutally clean house.
