The Royal Bank of Scotland chairman Sir Philip Hampton has told the BBC that allegations that RBS pushed small businesses into administration, and then bought their assets at a knockdown price, would be fully investigated.
Sir Philip added that RBS had kept alive tens of thousands of struggling companies.
The Serious Fraud Office is considering its own inquiry into the allegations.
