Anthropic hires its first UK lobbying firm as global AI policy push widens

Anthropic has hired its first UK lobbying firm to support its global AI policy efforts.

It is the latest step in a steady build-out of the company’s presence in Westminster. Anthropic now has former government insiders, a London policy team and a parliamentary track record, and it is adding professional lobbyists on top.

A Westminster roster that keeps growing

The lobbying hire does not arrive in a vacuum. It follows a run of senior appointments that read like a who’s who of recent British AI policy.

On September 2, 2026, Anthropic named Matt Clifford as managing director of international affairs. His remit covers government relationships outside North America, with a focus on the UK, Europe, Asia-Pacific and India.

Clifford is not a random pick. He drafted the UK’s AI Opportunities Action Plan, which was published in January 2025, and he maintained working ties with both the Sunak and Starmer administrations.

Clifford also continues to serve as chair of the Advanced Research and Invention Agency (ARIA) while working at Anthropic. That dual role has raised questions about potential conflicts of interest, even though the appointments comply with current guidelines.

He is not the only notable arrival. Lord Liam Booth-Smith, a former No. 10 chief of staff, has joined Anthropic in External Affairs.

Booth-Smith’s role comes with tight conditions attached. He is barred from lobbying for two years.

From voluntary pledges to binding rules

Anthropic has also been making its case in public. During parliamentary testimony on October 13, 2026, company representatives argued that AI safety standards need binding regulation rather than voluntary compliance.

The company’s push also extends below the executive level. Anthropic already has a dedicated Policy Advisor, UK role based in London, focused on engaging with the country’s legislative and regulatory processes.

Why Anthropic is building out its UK game

The UK sits in an awkward but influential spot in global AI policy. It is outside the European Union, yet closely watched by it, and it has spent recent years trying to position itself as a hub for both AI development and AI safety thinking.

The international affairs brief Clifford holds, spanning Europe, Asia-Pacific and India, suggests the UK is one node in a broader effort rather than the end goal.

What this means for the AI policy fight

The most immediate takeaway is that Anthropic is adopting a hybrid approach to influence. It is building in-house expertise through people like Clifford and Booth-Smith while also paying for outside lobbying help.

One plausible reading is that the external firm fills gaps the in-house team cannot. With Booth-Smith restricted from lobbying for two years, Anthropic may need other hands to carry out the direct advocacy work.

The questions around Clifford’s ARIA role show that scrutiny is already underway.
