Professional background

I have experience in acting for clients on a range of competition law matters, including CMA and Ofcom investigations, anti-trust compliance, vertical agreements, merger control and subsidy control. On contentious competition and regulatory matters I have represented clients in litigation before the CAT, High Court, Court of Appeal and Supreme Court.

Prior to a career in law, I spent six years working in public sector consulting and public policy.
