Heading up the Serious Fraud Office (SFO) is no mean feat. The quick thinking of criminals taking advantage of new technology to evade prosecution and the cross-border nature of many cases make chasing major fraud a frustrating as well as highly specialised task.

At the helm of the SFO is Robert Wardle, a lawyer and career civil servant. He has just finished his inaugural year in office, following in the footsteps of the high profile Rosalind Wright. Wardle has been at the SFO since its creation, a tenure of 16 years, and knows the department inside out. He began his time there as a case controller and had been an assistant director for just over a decade, before his surprise appointment last year.
