Vulture Funds
In summar: Vulture Funds is the term used to describe when US buisnessmen buy the debt of some of the worlds poorest countries then sue the governments for many times the value of debt.
One of the biggest vultures is also the largest donor to the US Republican Party. Sueing foriegn governments is illegal in the US without permission from the President so it could easily be stopped.
Gordon Brown has described the vultures as 'perverse' and 'immoral'.
