This letter was in the Guardian this morning:

The Guardian's investigation into offshore secrecy highlights a significant problem that is global in its impact. Developing countries lose vital resources for development through illicit capital flight, to such an extent that Africa is actually a net creditor to the rest of the world. Ending financial secrecy to expose corruption and tax dodging that hurts the poorest countries is a vital step in changing this reality: and that action must be global. We need a new international agreement to end the corporate anonymity and tax haven secrecy you have revealed. The prime minister has promised action at the G8, and our organisations will be working together next year to help make this happen. We are long overdue an end to the secrecy that denies resources to those in hunger and poverty.
