Sorry, I mentioned he was ill; I think it was obvious at the time that he was very ill, but it was a bit odd that it didn't seem to be mentioned, just that he was resigning because Foster wouldn't, iyswim. I sort of felt it was timed (and the announcement made) in such a way as to put maximum pressure on her, and cause as much strife as possible.
He could have "resigned due to ill-health" and they could have all got together and tried to set up the assembly again as soon as possible, but none of them seem to want to.
I think all of them are so busy scoring points off each other they seem to be just letting the important things slip by. They would rather "win" against each other than win, as a country, together.
