It would be irresponsible to treat a general election as a referendum. But the EU election? why not. All our traditional parties are totally split, except the Lib Dem mini party. We have the Brexit Farage party on the one hand, and the new pro EU dissidents party. The scene is set for a perfect popularist election if the EU elections take place. I bet that both Lab and Cons already realise this. It might be quite an incentive to get some sort of pseudo compromise which stops UK taking part in the EU elections.
