NATWEST's former head of fraud prevention quietly left his role earlier this year after the group found out he was working with a law firm specialising in bringing scam victim claims against banks.

A Natwest spokesperson told City A.M. that the bank took "appropriate internal action" against Jason Costain over his work with Liverpool-based CEL Solicitors.

Costain was likely in line for a £20,000 payment from CEL while still employed by Natwest, according to a judgment handed down in June and first reported by This is Money (Daily Mail) on Tuesday.

Paul Hampson, a director at

CEL, said his firm never paid Costain and that he never shared confidential information about Natwest. Costain reiterated these claims to the Mail.

Costain was involved with CEL between November 2020 and mid-2021, according to High Court documents.

Former CEL finance director Thomas Blanchfield said in court filings that Costain had access to hundreds of the firm's files, including successful claims against Natwest.

A Natwest spokesperson told City A.M: "The judgment in the proceedings did not make any finding that bank customer confidential information had been shared by our former employee with CEL."

CEL did not respond to a request for comment by City A.M., while Costain has been approached for comment.
