Users began tweeting they were having problems logging in to the app and website just after 9pm.

For some, a message popped up on some screens reading: "We are sorry that our internet banking is currently unavailable. Please try again shortly."

Others said they received a message saying the bank was having "technical problems".

One user tweeted: "Can't access the app or online to view accounts??? Not really ideal 2 days before Xmas and you need to work out budgets etc."

Another said: "Hi, is the app down? It won't let me log on to my internet banking."

Lloyds Banking Group said it was aware some customers were having issues and later confirmed that the problem had been resolved.

The issue lasted for less than an hour, a spokesperson said.

"Our online banking is working normally again," they said. "We're sorry some of our customers had issues for a short time this evening."
