"Referendum, general election and MEP election. "
I voted remain originally. In the GE I voted for a purported leaver. Apart from that, he was standing based on the sort of things I thought best represented me. I'm sure many people voted in both the GE and the EU MEP elections based on overall representation for the next 5 or so years rather than on one single policy.
Anyone claiming the GE was a another referendum is just building strawmen otherwise the tories would have won easily and not lost their majority. Or maybe all the leavers really did vote for leave candidates and that's why no one party won a majority. Because it's a cross party matter
