A pure coincidence.
On this occasion I don't think so.
There needs to be two events for their to be a coincidence and as far as I know there hasn't been a second one unless you count a possible announcement as one.
Therefore as I said earlier a damp squib.
Mind you bearing in mind we were led to believe there would be an announcement (which I thought there would be but not the one we hoped for) and the fact that there wasn't makes it not even a damp squib and just another non event.
I really am having my doubts about this now.
