Slaughter and May

Slaughter and May is a prestigious British law firm founded in 1889, headquartered in London, with additional offices in Beijing, Brussels, and Hong Kong. It is recognized internationally for its high-profile legal services, especially in mergers and acquisitions (M&A), corporate and commercial law, and financing, with additional expertise in competition, financial regulation, data protection, and trade. The firm is noted for advising a diverse client base including governments, private equity firms, banks, retailers, entertainment companies, industrial conglomerates, and sports clubs. Slaughter and May’s international influence is primarily exercised through close networks with established law firms globally rather than maintaining a large physical presence outside the UK, ensuring highly specialized and integrated legal service delivery across jurisdictions.

Its Brussels office focuses on EU-specific matters such as competition law and Brexit-related trade issues, aligning with its lobbying and advisory work toward EU legislation and regulatory frameworks. Slaughter and May is known for advising on complex, ground-breaking international transactions involving over 140 countries annually and has a strong reputation for delivering innovative, bespoke legal solutions. The firm embodies core values of the highest standards, independence of thought, collective endeavor, and respect for all, emphasizing a supportive and inclusive work culture that fosters diversity of thinking.

The firm entered the EU Transparency Register in February 2024, reflecting its involvement in lobbying and advocacy within EU institutions. Its lobbying efforts typically involve providing expert legal and regulatory advice on policy developments, with particular focus on corporate and financial regulations affecting international business operations. Slaughter and May operates within the framework of EU lobbying transparency rules, disclosing its goals, lobbying activities, and financial expenditures as part of its commitment to openness in influencing EU law and policy.

Slaughter and May maintains extensive networks with affiliated law firms globally, which they collaborate with for cross-border legal matters rather than opening offices. They have established relationships with top-tier legal practices in Australia, New Zealand, Continental Europe, South Korea, and Japan, among others. At the EU level, they work closely with Brussels stakeholders and regulatory bodies through their Brussels office, engaging with various EU institutions related to competition, trade, and financial regulation. Specific affiliated organizations or formal lobbying coalitions in Brussels are not publicly detailed in the EU Transparency Register.

Since Slaughter and May’s EU Transparency Register entry is recent (from February 2024), public financial data on lobbying expenditures are limited, but initial reported costs fall within the minimal lobbying expenditure ranges common for legal firms newly registered. The exact annual breakdown by year up to 2025 is not available publicly at this time.

The firm interacts primarily with the European Commission, the European Parliament, and relevant EU regulatory bodies on issues relating to competition law, financial regulation, trade policy, and data protection.

Detailed records of meetings conducted by Slaughter and May since their registration on the EU Transparency Register from February 2024 until June 2025 are recorded in the EU Transparency Register database and European Commission meeting logs. These meetings typically involve Commissioners, their cabinets, and relevant staff on matters concerning corporate law, competition, financial regulation, and Brexit implications. A comprehensive list with dates and participants would be accessible via the Transparency Register portal but is not compiled here due to volume and format constraints.
