So, the Tories AND Labour down by similar percentage points, decent increase for UKIP - massive swing to Lib Dems.
EDIT:- Lib Dems didn't stand a candidate in 2013, so that explains the big swing.
Yeah but the problem for Labour is that they are in opposition, both locally and nationally and a political rule of thumb is that while your in opposition your share of the vote is supposed to go up. In fact, leaders of opposition parties have lost their jobs if their share doesn't go up by enough.
I know it's only a local council by-election, and the turnout would probably have been very low, and Labour won't be targetting the Parliamentary Constituency of Sevenoaks. I think it does indicate something though - time will tell if they can turn it around.
