Coutts/Farage story is really about rampant Post-Brexit deregulation, an infrastructural attack via a corporate war on UK democracy. Dispensing with EU Banking regs means more risk is allowed that'll exacerbate the global financial crisis, taxpayers money can be gambled or fleeced when speculative deals fall through. Govt wants to abandon Brussels restrictions on banker bonuses.
@EuropeanPowell Farage is relying on EU laws (as implemented in the UK pre-Brexit).
Specifically, art 21 of the Charter of Fundamental Rights of the European Union, which (unlike the European Convention on Human Rights) provides against discrimination based on political opinion.
