lazy to make it equivalent, needs context. as noted, there is an expectation that the incumbent government does bad and the opposition does well. it is interesting to note that Labour have consistently lost seats in local elections since 2014. so par for the course really, people vote for change.
you seem to agree with my point, that there are other issues, more than a single trend. i agree there is a trend for remain areas to vote against the main parties, just dont think it fair to apply that nationally, to elections where other factors apply.
already acknowledged, UKIP loses are obviously lose of support for brexit. but else where its a tenuous link. was reading about Wirral where Labour lost seats to Greens, due to local opposition to the Labour council develpment plans for green belt. how many more seats are changing hands...
you cant say the vote is against Brexit (or anything), other than where UKIP have lost. consider Sunderland strong brexit vote, Labour loses 12 seats to Conservatives. could say thats a vote in favour of Brexit? across the country both main parties have lost but Brexit for and against cuts...
