The banking industry’s answer to 999 now covers nearly all UK current accounts as Monzo joins the anti-fraud service, with the digital lender recently facing criticism for its performance in tackling scams.

Monzo, which now boasts more than 9m British customers, has become part of the 159 hotline created by Stop Scams UK, an industry body backed by the Financial Conduct Authority and Ofcom.

Ringing the 159 number puts callers directly through to staff at their banking provider, who can give advice to help work out whether they are being targeted by scammers.
