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.

They show bankers helped clients evade tax and offered deals to help tax dodgers stay ahead of the law.

Former HMRC tax inspector Richard Brooks told the BBC the government had some serious questions to answer.
