HSBC bank: Ex-boss Stephen Green refuses to comment
Britain's biggest bank helped wealthy clients cheat the UK out of millions of pounds in tax, the BBC has learned.
Panorama has seen thousands of accounts from HSBC's private bank in Switzerland leaked by a whistleblower in 2007.
The man in charge of HSBC at the time, Stephen Green, was made a Conservative peer and appointed to the government.
Lord Green served as a minister of trade and investment until 2013. When confronted in the street by BBC Panorama, he refused to comment about the allegations.
