At the G20 this week, a growing group of G20 countries from France 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 leaders like David Cameron who opposed the tax have been left looking increasingly isolated.

This happened because millions of people like you forced the Robin Hood Tax to the top of the political agenda.

But it doesn't end here. Far from it. David Cameron remains one of the key blockers in the international process, 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.

We are now part of a movement of millions. From church services in St. Paul's to nurses on Wall Street, people everywhere are saying enough is enough. A Robin Hood Tax remains the best option on the table to start making the financial sector work for people, not just for profit.

Ideas this good don't come along every day. And when they do, they're too powerful to ignore.
