Her background as a City solicitor gives her particular strength in advising on fraud, bribery, and proceeds of crime offences. She has a detailed knowledge of SFO investigations and the negotiation and conclusion of deferred prosecution agreements. Katherine has a strong background in public law and civil proceedings meaning that she is well placed to advise in corporate criminal matters where there are questions of judicial review and/or parallel civil proceedings. She has recently been instructed in the leading case on dishonesty in the context of economic crime: R v Barton [2020] EWHC Crim 575. Recent work includes : advising a major global investment bank in respect of a bondholder fraud; advising G4S plc on the eighth deferred prosecution agreement to be concluded with the SFO; advising several FTSE-100 companies on major SFO investigations; advising an individual owner of a company under investigation by the SFO; and acting for Carlo Palombo in respect of his appeal against conviction in the EURIBOR proceedings.  Katherine is frequently led by the pre-eminent silks in corporate crime work and is increasingly instructed to appear in her own right.
