Recent lobbyist for Palantir had key role in helping Andy Burnham become PM Exclusive: Martha Dalton worked closely with Burnham’s team on byelection that secured his return to parliament
A recent lobbyist for the controversial $450bn US tech company Palantir played a senior role in helping Andy Burnham become prime minister, it has emerged.
Martha Dalton, whose company Lodestone worked for Palantir in 2024 and 2025, campaigned for Burnham in the Makerfield byelection that secured his return to parliament. She worked closely with his team on strategic communications and rebuttals, and was among supporters who clapped him into Downing Street in July.
Lodestone, which Dalton co-founded, worked for Palantir on projects including promoting its software at events in parliament where its engineers demonstrated AI-powered systems for use in British public services to MPs.
Dalton previously worked on the autumn 2025 deputy leadership campaign for the current education secretary, Lucy Powell, a few months after Lodestone stopped working for Palantir.
Her role emerged as Palantir fights to retain its £330m contract with NHS England to run the federated data platform, a national medical data system.
Burnham’s government is under pressure to scrap the deal . Campaigners are angry about Palantir’s work for the Israeli military in Gaza and Donald Trump’s ICE immigration crackdown. They have also raised concerns, acknowledged by NHS England’s chief executive, Jim Mackey, that the benefits to public health may not be as significant as has been claimed.
Lodestone’s work for Palantir and Dalton’s subsequent role with Burnham is the latest link between Labour and the tech firm, which also works for the US and UK militaries and was co-founded by the Trump-supporting tech billionaire Peter Thiel.
The Labour peer Tom Watson took a full-time job lobbying for Palantir earlier this month after a period as a member of Lodestone’s “strategic advisory council”. Palantir previously employed Peter Mandelson’s lobbying firm, Global Counsel, before it collapsed over the former Labour trade secretary’s links to Jeffrey Epstein.
Dalton wrote on her LinkedIn account that it had been “an absolute honour to work on Andy Burnham’s campaign to become Labour leader and prime minister”. She took six weeks’ unpaid leave from Lodestone to spend time in Makerfield “supporting on strategic comms and rebuttals”.
A spokesperson for Lodestone said: “She had no contact with clients during that time and did so because she believes Andy Burnham is the best person to lead the Labour party and the country. Lodestone had previously worked with Palantir on various projects – all focused on helping them to explain their technology to those who rightly hold them to account.”
