Mobile banking vans will be cut from eight communities in the Scottish Borders.
The decision comes after the bank announced the closure of 62 branches nation-wide, including five in the Scottish Borders.
RBS said it regularly reviewed its routes, based on customer usage.
From 28 April, the following branches are set to lose their weekly mobile banking service:
Greenlaw, Newtown St Boswells and Earlston will go from two visits a week to one.
The mobile branch will stop at Greenlaw for 20 minutes once a week.
I'm very angry, I know many of my constituency are angry too, businesses, pensioners, disabled groups, vulnerable groups, all these customers who are completely dependent on the bank branch network. "They're seeing access to banking services basically withdrawn from many of these communities. It's bad news for those communities which will be loosing out and I'm determined to continue this fight to try to make the bank reverse this decision".
