Also a possibility.
It is very easy for people to slip up. A few beers, a bit of banter, and information easily gets out. We have probably all seen the same at works social functions and parties. I have never met Ian Cheeseman, but he also struck me as a true blue. I don't imagine that he would do something to deliberately damage the club.
As for the case, the timings of what he revealed didn't stack up so I treated it as nothing more than a but of gossip, but highly unlikely. We all just have to wait. This is not the same as cases where other clubs were clearly briefed by individuals with vested interests. The tribunal panel is now effectively sitting in judgement and making their final decisions. Anything that is now revealed, in advance, outs a mole from a very small burrow.
