Martha Dalton, whose company Lodestone worked for Palantir in 2024 and 2025, campaigned for Burnham in the Makerfield byelection that secured his return to the House of Commons, according to an exclusive report. Dalton worked closely with Burnham's team on strategic communications and rebuttals, and was among supporters who greeted him at Downing Street in July.
Palantir, a US technology company valued at $450bn, has been a controversial presence in the UK due to its work with government agencies on data analysis and surveillance. The company has faced criticism from civil liberties groups over privacy concerns.
The report raises questions about the influence of corporate interests in British politics, particularly given the close working relationship between a Palantir representative and the prime minister's campaign team.
