Hang on Harry, the kippers didn't get any seats last round, due to the unfortunate blunder of forgetting their own name (lmao). Where are you getting that info?
As always the Mayoral elections will be done via the hilariously awful 'supplementary vote', which is like an attempt to do a Two round system without the expense of run-offs / do IRV while not trusting the public to count higher than '2'.
Simply by adding UKIP / Fresh Choice and UKIP on the regional list (after all they were votes cast for UKIP)
