The programme reveals how Scotland Yard woke up to the extent of corruption and the extraordinary lengths that the criminals would go to in order to undermine the police's ability to catch them.
The Pakistani city of Karachi is one of the biggest in the world - and now one of the most dangerous.

Mobeen Azhar joins Police Superintendent Ijaz and his team of Taliban Hunters as they try to regain control of the city.

John Ware hears from Muslims facing an angry backlash for trying to promote a form of Islam which is in synch with British values.
