financial services. Passporting ruled out by May with her redlines – basically you cannot get passporting without obeying EU rules in their entirity. Equivalence means staying very close to EU rules – again ruled out even tho the solution offered for NI means no regulatory divergence
So a deal on financial services that would allow the city to carry on in a similar way to now is extremely unlikely as to get a deal means UK would have to follow EU rules very closely. Something that Johnson, Gove, Davis will not allow and categorically ruled out by May
So Free movement of capital cannot be divorced from the other 3 freedoms, May has ruled out allowing free movement of people and also ruled out regulatory convergance. so no deal on financial services.
remember there is zero incentive for the EU to compromise on this. No deal means all financial services that involve the EU move out of london and that is to the EUs advantage – and the scam to open shell companies / subsidiaries has also been categorically ruled out as computer systems, senior staff and processes all must come under EU law.
