Former Co-op Bank boss Paul Flowers has admitted he has "sinned" in his first interview since the furore erupted.
Mr Flowers was bailed in connection with alleged drugs supply offences in January.
The Methodist minister stepped down as the bank's chairman in June amid claims of illegal drug use and inappropriate expenses payments.
In an interview with BBC2's Newsnight, he said: "I am in company with every other human being for having my frailties and some fragility exposed.
"Most people get through life without that ever coming into the public domain.
"But, of course, I have sinned in that old-fashioned term, which I would rarely use, I have to say."
