With the Government claiming to lead the way in plans to crack down on global corruption, how come so little is being done in Britain to tackle the vast sums of money allegedly laundered through the UK by corrupt foreign officials and international crime gangs? Allan Urry investigates claims that not enough is being done by the UK to tackle the laundering of corrupt assets or to assist nations who ask for help in getting their money back. The programme also hears complaints that British law enforcement is refusing to investigate cases. Reporter: Allan Urry Producer: David Lewis.
