"We need to break free of the dead weight" You also need to look at how they became dead weight and why they feel differently - I'm going to project a bit but I'm guessing they'd say that Londoners were out of touch with the rest of the country. It's a shame that the ruling elites have become so good at disenfranchising their constituents. Let's take the idea of an independent London to a humorous conclusion. I'm imagining the rest of the country building a "Trump Wall" around London to keep the undesirable elitists contained in their fancy playground. Then heavy tariffs on imports and exports on trade. Those who live outside London but provide the rudimentary services will dramatically increase their prices (you still can't make due in London without four maids and a cook!) which will, combined with tarriffs/taxes levied by the non-Londoners will improve the GDP of the rest of the country dramatically. So in the end, those who voted to leave the EU because they weren't benefiting from the economy between the UK and the EU will start benefiting - the Londoners will have no choice but to share. And that's all the proletariat wanted to begin with.
