Transparency campaigners have called for thinktanks to be more open about their funding sources, after it emerged that some of Britain’s most influential ones received more than $1m (£787,000) from donations in the US in 2021.
They include the Institute of Economic Affairs (IEA), regarded as an inspiration for policies adopted by the Liz Truss government, and Policy Exchange – a conservative thinktank used as a platform by ministers to trail new measures and which recently incubated hardline immigration plans.
