The London office, established in 1997, has a longstanding reputation for handling high-profile and complex cases.

The firm advises clients including multinational corporations, financial institutions, sovereign states, early-stage companies, and individuals.

The London practice is active across a wide range of areas. Its commercial dispute resolution team handles large-scale international litigation involving shareholder and joint venture disputes, banking litigation, complex civil fraud, competition-related High Court cases, corporate reputation, and regulatory investigations. The competition practice advises on EU and UK competition law, representing clients before the UK Competition and Markets Authority in matters including merger control, foreign direct investment, and abuse of dominance, with notable strength in pharmaceuticals, life sciences, consumer goods, and media.

The corporate team advises on domestic and cross-border M&A, joint ventures, strategic alliances, public takeovers, shareholder disputes, venture capital, and mid-market private equity transactions. Data protection services include compliance projects for multinational companies and incident response, particularly for clients in the financial, media, technology, and life sciences sectors.

The employment team advises on all aspects of employment law, including business immigration and the employment aspects of mergers and outsourcings across multiple jurisdictions, with a strong client base in life sciences, technology, and retail. The finance team acts for investment banks, private equity funds, and financial institutions on banking, leveraged finance, structured credits, derivatives, and debt capital markets, including representation of sovereign issuers.

The intellectual property and technology practice provides strategic advice, dispute management, and litigation support across patents, trademarks, copyright, database rights, design rights, and trade secrets. The international arbitration practice handles both ad hoc and institutional proceedings, representing sovereign governments and private investors in disputes under concession agreements, bilateral investment treaties, and international contracts.

The firm also advises on investment management, including the structuring and regulation of funds and compliance with AIFMD, MiFID, FCA rules, and SEC provisions. The life sciences practice, one of the largest in Europe, covers regulatory issues across the product lifecycle, including emerging technologies such as gene and cell therapy, digital health, and pharmacogenomics.
