Re: In hindsight
Disingenuous
Because, as you say "Both Labour & Conservatives at post 2016 elections promised to..." etc But that doesn't actually leave voters any realistic alternative options. A vote for the minor parties in the UK ( or at least England) is seen, correctly, as giving a vote to the incumbent in almost all constituencies. Add to this the plain and simple fact that for most voters there are other issues to vote about - especially since there was no realistic chance of a minor,pro-EU, party winning anyway.
