Dear Gordon Brown, David Cameron and Nick Clegg
It’s time for banks to pay their fair share.
We call on you to support a “Robin Hood Tax” on banks. It’s a small tax on high value transactions between banks that would raise hundreds of billions of pounds that would be used to fund action against climate change, poverty and other big issues in Britain and around the world.
Together we can turn the banking crisis into an opportunity for Britain and the world. Please support the Robin Hood Tax.
