TSB has said it will cut around 900 jobs as part of plans to close 164 of its high street bank branches.
TSB chief executive Debbie Crosbie said: "Closing any of our branches is never an easy decision but our customers are banking differently - with a marked shift to digital banking.
"We are reshaping our business to transform the customer experience and set us up for the future. This means having the right balance between branches on the high street and our digital platforms, enabling us to offer the very best experience for our personal and business customers across the UK.
"We remain committed to our branch network and will retain one of the largest in the UK."
