EU Brexit negotiator also figures it out. Yes. London is the biggest financial centre in the world and Europe needs finance.
There's no special case for London. It's the UK that is leaving the EU and - guess what - the EU is going to end up giving the UK a fair deal. The bullying, hardline negotiation is going to break in favour of a sensible, constructive, mutuallistic conversation because that is the optimal solution.
Silly, nasty, arrogant people in Brussels.
