Barclays bank is planning to close up to 200 of its smaller high street branches next year.
The move comes as traditional clearing banks see increasing numbers of customers switch to other forms of banking.
Barclays is the second biggest retail bank after Lloyds TSB, with 1,900 branches. The latest closures are in addition to the 50 planned by the end of the year.
The bank announced plans to shed 6,000 jobs in May. The shake-up will cost £345m but is expected to save £220m a year.
