It's the latest in a line of glitches at the bank

Ulster Bank has apologised to customers after an issue affected their online and mobile banking this morning.

People found themselves locked out of their accounts - however ATMs and telephone banking were unaffected.

In a statement, they said the issue has now been resolved and that no customer will be left out of pocket.

The problem also affected customers at the Royal Bank of Scotland and NatWest in the UK.
