I really have very little idea, but why should that stop me making a suggestion?!
I’d say that Labour might well get a bit of a hammering in Wales, leading to a pretty evenly divided Assembly, is some kind of LibDem – Plaid – Tory collation a possibility, I seem to remember it being suggest a little while back?
As for Scotland, the SSP will probably collapse (is Sheridan still in the parliament? If he is he must be the only one with a chance of retaining his seat I would have thought), Green and LibDems no doubt make some advances, as well as probably the Tories while Labour fall back a bit… no idea about the SNP (further decline?). End result continuation of the current collation with a heavier LibDem contingent and the possibility of temporary alliances with the Greens and/or the Tories?
Please feel free to say this is all complete cr*p
