HSBC tax scandal: Was Inland Revenue tough enough?

A panel of MPs will launch an "urgent" inquiry into tax evasion by wealthy clients of HSBC.

The Public Accounts Committee plans to investigate the scandal and will require HSBC to give evidence, according to its chair, Margaret Hodge.

The BBC learnt that HSBC helped wealthy clients evade hundreds of millions of pounds worth of tax.

Business Editor Kamal Ahmed reports on whether the Inland Revenue could have done more to pursue HSBC's customers who evaded tax payment.
