Charlotte has a strong reputation in the Business Crime field, with expertise in domestic and international corporate crime disputes/investigations; complex fraud, corruption and money laundering matters; sanctions, extradition and INTERPOL cases; and private prosecutions.

Since joining Peters & Peters in 2010, Charlotte has represented clients in some of the most high profile and high value cases in recent times, acting for individuals and corporates in a broad range of sectors including government, royalty, entertainment, finance, construction, engineering and retail.

Charlotte is recognised as a 'Rising Star' in Legal 500 2023, and is being noted for her international practice, with standout involvements in areas such as sanctions, extradition, and cross-border business crime proceedings. Her previous listing as a 'Rising Star' in Legal 500 2022 quotes "Charlotte Tregunna should be the first name on any list of rising stars in the white-collar crime world. She is bright and ferociously hardworking, but with real practical instincts. She is also exceptional at dealing with difficult clients".

Charlotte specialises in advising clients facing domestic and international internal, criminal and/or regulatory investigations, including those brought by the Serious Fraud Office, the Financial Conduct Authority, the Competition and Markets Authority, the City of London Police, US Department of Justice (DOJ) and Securities and Exchange Commission (SEC).

Her private prosecution experience includes assisting the team that successfully prosecuted what was then the highest value private prosecution brought by an individual (R (Mirchandani) v Somaia) and more recently acting in the largest and most complex post-conviction disclosure exercise in UK history in the Court of Appeal proceedings, Hamilton & Others v Post Office Limited.

Charlotte’s cases frequently have an international dimension, requiring close cooperation with jurisdictions including those in the EU, Switzerland, Russia, Ukraine, and the UAE. She has had success in discharging extradition requests from India, Greece, and Russia, including the case of Egorova & Others, the leading case on the UK’s approach to/treatment of women facing Russian extradition requests.
