About this episode
Dubbed the biggest rogue trader in British history, Kweku Adoboli ran up $2.3bn of losses for the Swiss bank UBS. He has spent four years in prison for fraud and now faces possible deportation from Britain back to Ghana. He maintains he was not motivated by greed but that the system put unbearable pressures on him to make big returns. He warns that the culture of the banking industry has not changed very much which means it could easily happen again.
