More than one in 10 people picked for the top jobs in British finance pull out during a regulatory vetting process which has become tougher since the financial crisis.
People put forward for chief executive, chairman and for a handful of other senior roles in banking now face a more grueling interview by British financial watchdogs.
This increased scrutiny also follows weaknesses in vetting exposed by problems at the Co-Op Bank, where the former chairman, Paul Flowers, was waved through in 2010 despite disclosing a criminal conviction and later showing little knowledge of banking.
