Signature Litigation LLP

Banking Litigation, Commercial Litigation

Becca specialises in high‑value, complex commercial disputes, with a particular focus on banking and financial services, securities litigation and group actions. She also advises on contentious regulatory matters, including FCA investigations.

Her recent work includes representing a group of institutional investors pursuing claims exceeding £560m against Barclays Plc under FSMA s.90A, arising from alleged fraud and misconduct linked to Barclays’ liquidity dark pool. She has a long track record in securities litigation, notably acting for a large institutional and retail claimant group in the groundbreaking s.90 proceedings against the Royal Bank of Scotland and its former directors.

Becca is a lead partner at Signature defending Renault in the unprecedented NOx Diesel Emissions Group Litigation. In 2024, a Group Litigation Order was made in respect of Renault—one of 14 GLOs in the Pan‑NOx Emissions Litigation, which encompasses claims by more than 1.5 million claimants against multiple manufacturers. A 10‑week technical trial is listed from October 2025. The case involves highly complex issues regarding diesel engine design and operation and requires close collaboration between Signature’s London and Paris teams.

She has also acted in substantial fraud and conspiracy matters, including defending the former management of a Thai renewable energy company in a US$2bn dispute over a 19‑week trial.
