He robbed from the rich and gave to the poor -- and that's why Occupy Vancouver protesters will be marching in support of Robin Hood today.

Participants of the Occupy movement around the world are expected to rally in favour of a so called "Robin Hood tax."

They want G-20 leaders to impose a one per cent tax on all financial transactions and currency trades, arguing it would generate massive amounts of cash that could be used to help society.

Vancouver police say they'll monitor the march this afternoon along with Occupy protests planned for Sunday at a downtown cathedral and another Monday near a Skytrain station.
