Global campaign group, Avaaz will deliver a 720,000 signature petition to the MEPs today calling for rigorous sanctions against bankers.
The petition calls for "strong legislation against market abuse, including criminal sanctions for bankers who ride roughshod over regulations or break our laws".
People across Europe want to see bankers behind bars. They are massively rewarded for their reckless gambles and get off far too lightly when caught.
720,000 people are today urging MEPs to agree that no banker is too big to jail.
