Millions still affected by NatWest and RBS computer glitch The banks, which are part of the taxpayer-owned RBS Group, said that "technical issues" with its computers meant that payments in or out of accounts have been delayed since late on Tuesday night.

Around 1,000 branches will stay open until 6pm on Sunday to give customers access to their cash and help with enquiries. They will also open on Sunday, a spokesman for RBS Group said. It is the first time in the banks" history that they have opened branches on such as a scale over a weekend. The RBS Group spokesman said that it is working "round the clock" to resolve the issue. He added that "no customer will be left permanently out of pocket" by the IT failure. The problem occurred following a bungled computer software update by the group late on Tuesday night. The banks have around 2,000 branches in total.
