Robin Hood Tax or Tobin Tax

I saw a piece on the television this morning about the Robin Hood Tax and I was thinking how similar it was to the Green Party Tobin Tax policy, when they said they had renamed the tax to one with a more appealing name. Basically, bank transactions not directly involving customers -- a bank to bank transaction for example -- are taxed at a very low rate, 50p per thousand pounds for example to dampen down the global casino economy and raise funds for worthy projects such as ending child poverty at home and abroad.
