Serious research, yes. Headline-grabbing pseudoresearch (of which there is a lot these days), if it helps with the donors, then possibly. It comes down to the question of whether he'd still have enough pull among the Islingtonistas to make it worthwhile for some organisation or other to give him a go. I don't know about that. He has a few defenders knocking around, though, so despite the parody he's getting online, his name isn't completely mud yet, it seems.
Partly depends if he's outright sacked, or quietly 'agrees to move on' once things have died down in a few weeks. If the latter, he'll have much greater 'pull' factor.
