Nice in theory, but only works in practice if every other country does the same. Good luck trying. I'm sure plenty of countries would love to see the UK do this
'At the G20 this week, a growing group of G20 countries from South Africa to Brazil backed the Robin Hood Tax, and the link between the Robin Hood Tax and fighting poverty and climate change became clearer than ever. Momentum is building and leaves leaders like David Cameron who opposed the tax looking increasingly isolated having sided not with the 99% suffering the effects of the economic crisis, but the interests of a privileged few in the financial sector.
As expected, Bill Gates presented an excellent report calling for a 'Robin Hood Tax' on financial transactions to raise much-needed money for poor countries struggling to cope with the economic crisis and climate change. Bill Gates's report is a game changer - it shows that a tax is both feasible and desirable but crucially that countries can no longer hide behind the excuse that financial transaction taxes needs to be global to work.
Whilst G20 leaders could have gone further, this is far from the end. Events in recent days, with Mr Gates' call being supported by G20 members from France, Germany, Argentina, South Africa and Brazil and by senior figures from the Archbishop of Canterbury to Jeff Sachs, it is clear that momentum is building behind an idea whose time has come.
David Cameron remains one of the key blockers in the international process with even the USA and Russians moving, so it?s vital we keep up the pressure on the UK government ahead of EU talks next week and UN climate talks in South Africa in December. And here in the UK, as the economy fails to pick up and cuts to public services continue to hit ordinary people, we need to keep the pressure on Cameron ? this is Plan B. '

Remember this when Cameron is banging on about how the cuts are necessary. And how we're all in it together.
