The BBC has claimed that NatWest has suspended its Get Cash app - which allows customers to get hold of cash from ATMs if their debit card is forgotten, lost or stolen.

A report on Radio 4's Money Box programme revealed that one customer reported being defrauded by criminals taking advantage of the scheme - and there were claims that the bank was withdrawing the service as a result. NatWest says this is not true. So what's going on?
