I think democracy and underrepresentation are different things and it seems most don't see the difference. Would London be more democratic as a separate state?

I think democracy and underrepresentation are different things and it seems most don't see the difference. Would London be more democratic as a separate state? They voted to stay in the EU but it seems their vote doesn't count much as the UK leaves the EU. Does it make the UK undemocratic? Of course not. I think the idea behind EU is that united you can accomplish more(at least on long term). It's democratic but like any democratic system it has multiple players. UK left it because it couldn't control it not because it was not democratic. That's not necessary a bad thing for the rest of EU
