What is The Robin Hood Tax?

Around the world, momentum is building behind a tiny tax on bankers that could generate billions to help with problems at home and overseas.

It has been given different names in different countries – the ‘Robin Hood’ tax in the US and United Kingdom, ‘Steuergegenarmut’ or ‘tax against poverty’ in Germany, the "Robin des Bois" in Canada and France, "Zerozerocinque" in Italy and "La Tasa Robin Hood" in Spain, but we are all talking about the same thing: a tiny tax on the transactions of big banks that could deliver billions to help ordinary people and fight poverty around the world.
