More than a third of people working in the UK investment market are considering leaving the country after Brexit, or are already making plans to do so, amid fears Britain will depart the European Union without an exit deal.

In a survey of 1,203 asset management staff conducted by CFA UK, the professional body, just 65% said they intend to continue working in the country post-Brexit, compared with 86% before the 2016 referendum. The remainder are either undecided or looking for employment outside the UK.
