The Bush family, the Saudi Royal family, Osama Bin Laden's family and Donald Rumsfeld's inner circle - these are just some of the high profile figures who have played a direct role in the rise of one of the most powerful and influential and secretive firms in Washington.
The company is called The Carlyle Group. And in the wake of the events of September 11th and the invasion of Iraq, its power and influence have become significantly stronger.
The company operates within the so-called iron-triangle of industry, government and the military. Its list of former and current advisers and associates includes a vast array of some of the most powerful men in America and indeed around the world.
This program exposes the history of the Carlyle Group, from it's inception as a private equity firm to it's precent status as one of the largest defence contractors in the world.
