Around half of senior finance executives polled by Big Four accountancy EY expected Brexit to drive more jobs out of London, despite prime minister Boris Johnson’s claims that the City remains an attractive destination for bankers to continue doing business.

EY asked 43 bosses at London’s banks, asset managers and insurance firms in mid-October if they expected their firms to shift more people or assets to the European Union as a result of the UK’s split from the bloc. Just under half, or 48%, said such moves were likely, including 8% who said they expected their firms to shift “a large extent” of people or assets in the foreseeable future.
