What was the turnout in Corby? I know that for one of the by-elections in Manchester, turnout was very low - 25% or something, which did surprise me a bit.Was the turnout in Corby also low?
It has to be considered a good result for Labour - Mensch had a majority of 2000 at the General Election, so this represents a pretty large swing to Labour. Much of that swing and dissatisfaction will be down to Mensch quitting her role, but a lot will presumably be a protest vote at government policy.
Lib Dem vote has collapsed, and were I Nick Clegg, I would be extremely worried at what this means for the Lib Dem vote at the next general election.
