An investigation by the BBC's Newsnight and the Guardian has discovered that an American so-called vulture fund is planning to extract a small fortune from the Democratic Republic of Congo.

Previous Newsnight reports on vulture funds - which buy up debt cheaply and then sue developing countries for vast amounts - got the laws in the UK changed. As a result, the vultures now cannot use UK courts.

But they have found a way around the ban by filing law-suits in the island of Jersey.

Greg Palast's report begins in the Democratic Republic of Congo.
