Walter,
My apologies for saying this but I'm not sure that your conjecture (or any other, nothing personal) is relevant at this late stage. We can neither prove or disprove conjecture.
Unfortunately, due to my present personal circumstances I do not have time or wish to go into a protracted argument of semantics but I could also think up a number scenarios that would fit the circumstances. I wholeheartedly agree that any number of factors not discovered or even undisclosed might have been very relevant, not that I am saying there was a conspiracy of any sort.
The news about Mr Major is very welcome. How glad I am that our persistence is beginning to make more and more people, now including the Prime Minister of the time, realise that a great injustice has been done and needs correcting.
