Plaid say no!
From the BBC Wales website: "Plaid Cymru has reacted to newspaper reports suggesting there could be a "grand coalition" of opposition parties in the Welsh assembly by dismissing the idea. The party said Plaid assembly leader Ieuan Wyn had ruled out a coalition "absolutely" in November, and there had been no change. Plaid said this view was also shared by both its AMs and national executive committee." Well that is alright then!
