if you go by official party positions, not gray areas, soldier of the king is actually right and you're not, Conservatives and Labour are a mess, but look at their official websites and they say they respect the referendum and Britain will leave the EU, labours website says;
"Labour respects the result of the referendum, and Britain is leaving the EU. But we will not support any Tory deal that would do lasting damage to jobs, rights and living standards."
if you don't believe the above statement, please check labours official website, thanks
While its never as simple as official terms and its never black and white, I am afraid its the only measure to really judge, as gray areas can be used to justify any position, ie like the well known "tradition" of just backing lib dems when your fed up with the big two parties and how the SNP only matter in scotland and they were treated like a separate remain entity back in 2016, but now being used as a part of the bigger picture by remainers when it suits.
So by official statements to the electorate Conservatives and Labour respect the referendum and the UK will leave the EU.
So officially 57.7 = leave and 41.2 = remain and the left over is independents. the gray areas are subjective, as their is entire paradoxes on the way people vote. ie there is still people who vote lib dems as the protest vote out of habit and how even an anti-eu person who is a eco-fanatic would still vote greens, also the fact there is both labour and conservatives who are remainers, even though their parties officially respect Brexit. But sadly for you, official stances only matter as that's what people are officially voting for.
But you'll come back with more spin to refute this. carefully lumping the remainers into one mass, while splitting the leave vote into "hard Brexit" and "soft Brexit" all the pro-EU sites are comparing remainers specifically to "hard" Brexit parties, dismissing the fact Conservatives and Labour are officially leave with deal at time of elections, but even if you think conservatives/labour are messing up Brexit and have false intentions, their positions of leaving with a deal, is still a leave policy.
