Well this will have soured Boris's porridge this morning! That is a huge turnround and while all sorts of spin will be put on it the Tories will be having a WTF happened meeting sometime soon!
Labour vote almost totally collapsed but this won't bring Sir K down as it would be stupid of Labour to take the media's eye off the Tories. They will be looking to see if this is the start of Labour votes going to Libs, which is a real possibility. Labour voters so pissed off with the Party that their vote will go to Lib Dems - run that over the country and we could see the Party fortunes between the two swapping.
This will have made a great start to the weekend for @wetsmonkey
Why would a Conservative voter cheer the loss of a safe seat to the Lib Dems?
