FCA chief executive Martin Wheatley and chairman John Griffith-Jones will face a grilling from MPs next week as part of their bi-annual scrutiny by parliament.
Wheatley and Griffith-Jones will appear before the Treasury select committee next Tuesday at 10am.
TSC chair Andrew Tyrie told Money Marketing he wants the FCA to undergo a culture change as big as banks.
He expressed concerns that the positive FCA “tone at the top” would not be transferred down to staff at the coalface.
The FCA chiefs are also likely to face questions on its thematic review of the annuities market, set to be published in the next couple of weeks.
Wheatley and Griffith-Jones could also be asked about the impact of the RDR and the existence of the advice gap.
Last July Wheatley said he had “concerns” about an advice gap and said it could be filled by web-based solutions.
Tyrie says the TSC could launch an inquiry into the RDR impact but the timetable means it is unlikely before the May general election.
