re 4. I strongly suspect that they've ballsed this up anyway. London had a lot going for it for clearing / financial services, one of which things being that there was a mature, (strong and...) stable government which wouldn't do stupid things to interrupt companies businesses. Whether that's good or bad, you decide.
However, even if they cancelled Brexit tomorrow, they've lost that reputation - and they'll never get it back. I imagine there'd be a lot of CEOs looking at London and wondering if a little geographic diversification in their companies wouldn't be a bad thing in any case in the light of all these recent ludicrous referenda / elections.
