The UK's financial services firms want better communication from the markets watchdog on Brexit planning, according to a survey of institutions the Financial Conduct Authority oversees.

The poll of more than 2,000 firms found a third were unhappy with the clarity of information provided by the FCA on the process of preparing to exit the European Union, while a further 53% of respondents were undecided. Just 14% were satisfied with the regulator's communication on the topic.
