About Polly Sprenger

Polly Sprenger represents corporate and financial services clients dealing with allegations of commercial misconduct including fraud, corruption and money laundering. She handles criminal and civil litigation, conducts internal and cross-border investigations, and advises clients on criminal and civil breaches of the Data Protection Act and other privacy-related issues.

Former high-level fraud prosecutor, investigative journalist

Working closely with Katten's global team of experienced investigative lawyers, Polly helps her clients with civil and criminal remedies for multiple types of corporate misconduct, including defending government enforcement actions; bringing private prosecutions; production, disclosure and freezing orders; civil recovery and asset tracing; and evidential considerations of conducting internal investigations. She previously served as head of Strategic Intelligence at the UK Serious Fraud Office and worked for several years as a corporate investigator and investigative journalist.

Polly's work also draws from experience serving as junior counsel in the high-profile prosecution of News of the World journalists and employees, and as technical advisor to a 2012 Parliamentary inquiry into private investigators and phone hacking.

Her advisory work extends beyond legal remedies into managing reputational issues and crisis planning, preparedness and response. She advises a growing number of corporate clients grappling with allegations of sexual offences in the workplace.
