naomi, I did read the link. I just don't happen to believe it. Marchessini didn't make it "absolutely abundantly clear that he is no longer associated with the party at all" - he merely said he supported Ukip because of its policy on Europe but would no longer give money to it. The absolutely abundantly stuff appears to come from Ukip, trying to keep him at arms' length, not the other way round.
But he won't be switching to the Tories any time soon:
The National Debt under Mr Cameron will increase by £700bn in five years. This is equal to its total for the previous 100 years. Austerity!
