US Senate report: HSBC 'used for money laundering'

A US Senate probe has disclosed how lax controls at Europe's largest bank left it vulnerable to being used to launder dirty money from around the world.

The report into HSBC, released ahead of a Senate hearing on Tuesday, says huge sums of Mexican drug money almost certainly passed through the bank.

Suspicious funds from Syria, the Cayman Islands, Iran and Saudi Arabia also passed through the British bank.

HSBC said it expected to be held accountable for what went wrong.
