Bank of England investigating claim Metro Bank put customers’ data at risk

Exclusive: Whistleblower raised concerns about security of in-branch coin-counter software

The Bank of England is examining claims that the high street lender Metro Bank put customers' data at risk by allegedly misusing software at the centre of a long-running legal dispute.

Last month the central bank's whistleblowing team was contacted by a person raising concerns about the integrity and security of software used to connect Metro Bank's in-branch coin-counters - known as Magic Money Machines - to customer accounts.
