A few months ago Harry Hayfield, PB’s local election specialist, introduced a new element in his regular monitoring of local by-election: dividing them up into whether the local authority areas voted REMAIN or LEAVE on June 23rd. This enables us to compare the two areas.
A lot of focus has been put on seat changes but the above data looks at how the vote shares have changed in the two types of seat. The vote change relates to what happened in the wards in comparison to when when they were last fought.
We all know that the LDs have been having a particularly good time in local by-election of late but I was quite surprised by the vote share changes that have the most pro-EU party doing far better in places that voted for BREXIT than those that didn’t.
Turnout, of course, is a key factor. The referendum saw it top 70% in most parts of England while in local by-elections he number of voters participating is a lot fewer so you cannot assume that the make-up of by-election voters will reflect the referendum pattern.
