The Financial Conduct Authority would prefer the new, stricter approval process that is being brought in for senior bankers to cover not only banks but firms across the finance sector, according to Clive Adamson, the regulator's director of supervision.

The UK is introducing a new process under which regulators will sign off on the appointment of senior bankers, replacing its previous Approved Persons Regime, which has been criticised by politicians as too weak and cited as a contributing factor to the UK's banking crisis.
