I think Alison has explained what she meant by that comment: the intention of her Foundation-l comment was that she held concerns a new WER board being "under the cloud of the previous (less successful) board," as opposed to her not trusting the new board and therefore not supporting their replacing her.
I haven't seen that explanation and I don't see how her words can be interpreted in that way. She was pretty clear.
At least, that's what I hope it meant. Alternative interpretations are a little more concerning: one would hope that the current board would hold enough trust in the wider WMUK community for them to support members from that community replacing them at the next election.
Sure, one would have hoped that, but the facts would suggest otherwise.
