The chair of the UK's influential Treasury Committee has urged the City's top policymakers and regulators to waste no time in analysing the impact of any final Brexit deal on financial firms.

Nicky Morgan has written to Chancellor of the Exchequer Philip Hammond, Bank of England governor Mark Carney and Financial Conduct Authority CEO Andrew Bailey to demand in-depth studies on the implications of any deal on the future of UK financial services "in good time before Parliament comes to make its key decisions".
