NATWEST has apologised after users of its online banking services were left locked out of their accounts.
In a statement sent to customers the bank said: "We are sorry if you are having trouble getting into our online banking or mobile app.
"We are working hard to resolve the issue. You can still access your account through telephone banking or alternatively you can visit one of our ATMs."
The glitch came a day after some Barclays customers were left struggling to log in to their accounts due to a technical problem.
Royal Bank of Scotland confirmed its brands — NatWest, RBS and Ulster Bank — were facing service outages for mobile and online banking.
RBS had said: "We are aware that customers are currently experiencing issues logging into their online and mobile banking accounts.
"We would like to apologise for the inconvenience. We are aware of the problem and are working to fix the issue.
"Customers can still use ATMs and telephone banking."
RBS/NatWest has confirmed the problems have been resolved.
A statement from the bank said: "We would like to apologise to customers who experienced issues logging into their online and mobile banking accounts this morning, this issue has now been resolved."
