I'd say that London is basically operating as it's own Global City-State in it's own City-State interests and aggressively seeks to annihilate rival City States in order to get more money and power for itself. Before it's at least been tethered to the EU and EU rules. Whereas now it's going to potentially be floating free, largely unrestrained. If it sees a potential rival it's going to take co-ordinated action to defend itself. I.e corporations HQ potentially leaving for Berlin, the suggestion was raised that we'd now have the lowest corporation tax in the Western World which is liable to decimate Ireland for starters.. The City has a weird economy, that can do weird things and put itself into siege mode for years. Before at least when it was part of the larger Empire it coordinated and fitted into a larger game plan of logistical retrainedness and followed a chain of command. Now it's controlled entirely by Ewoks it's going to float around without any sort of larger team to be part of. If the [now enemy] neighbouring star destroyers start restricting the biscuit supply to the detriment of the Ewoks, the Ewoks are going to laser beam them I would have thought.
