There was no evidence at the time he was competing that lc was a cheat. After he retired and had moved on to a media career (presenting record breakers! ) he was caught using something at a race he was just doing for fun as far as I can remember. He then left record breakers...
The period is generally thought of as dodgy to the point that authorities have considered wiping all records between certain dates. But there's no evidence he cheated at the time, and I choose to believe that. Those gb medals were few and far between in those days!
Also I think his clothing choice was just ahead of its time. A real stretch to suggest pervy motives. Lycra wasn't as good then. Technical fabrics have really developed.
I agree I don't think he's likely to be a great ally in this though.
