I just did a short piece on Radio 5 Live about the Norwich North by election, alongside the LibDem supporting Norfolk Blogger, Nich Starling. Nich said something which gave me real pause for thought. He believes the Labour vote is going to collapse so dramatically that Labour will come third. He didn't go so far as to predict a LibDem win (wise boy) but he is absolutely convinced that Labour is in for an absolute hammering.
My own view is that the turnout is going to be dreadful and that many Labour voters will simply stay at home. But Nich possibly underestimates the solidity of the Labour vote in the City wards. It will be interesting to see what they do. If they do turn out to vote then Chloe Smith is in for a fight. If they don't, well, we'll see.
But let's imagine that Nich is right. If Labour came third, what effect would that have on Labour MPs as they troop off for the summer?
