HG... as I said to you over on my own forum.... I don't think that Brown's tenure as party leader is going to last much longer in any situation, never mind his position as Prime Minister.
I am sure though that the Labour group are going to be throwing some REALLY juicy bones at the Liberal democrats if they decide to throw in with them.
Of course this kind of a deal would also mean that the votes of the three national parties of Ireland, Scotland and Wales, plus The Greens, would be needed to make up a working majority.
A VERY complex solution, I think !
