Serious Fraud Office (SFO) director David Green QC has been tipped for a lucrative move to a US law firm when his leadership term at the regulator ends next year, according to City white-collar crime partners.

Green, who has led the SFO since 2012, is set to step down next April after being handed a two-year extension to his original four-year term last year. He has overseen a number of key successes during his tenure, including the deferred prosecution agreement (DPA) with Rolls-Royce earlier this year, which will see the company pay out £671m following a four-year bribery and corruption investigation.
