Financiers in the Square Mile back Boris Johnson to win next month’s general election, even though the majority of executives working in the City believe the Brexit deal brokered by the prime minister would be bad for London’s financial district.

According to an exclusive poll by Financial News of more than 100 executives working in financial services, 56% said a Conservative Party victory would be the best outcome for the Square Mile, with a further three-quarters of respondents believing the Tories are the natural governing party for the City.
