On May 22, Great Britain voted for local government posts in many places, and also for representatives to the European Parliament. This article says that partial election returns for local races show that the UKIP (United Kingdom Independence Party) made substantial gains, and that the Green Party also gained. Results of the European Parliament voting won’t be known until Sunday. Those returns will be even more interesting, since proportional representation is being used for the European Parliament elections. Thanks to J. David Gillespie for the link. UDATE: this story has more detailed election outcomes.
The UKIP plurality wins in the local regimes may actually cause/force the Cons-LibDems to have P.R. in ALL of elections in the U.K. — i.e. to prevent the leftwing Labour folks from winning in the 2015 gerrymander election — due to divide and conquer plurality math.
