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.
