From HS2 cancellations to Heathrow’s still unbuilt third runway, the over-budget Elizabeth Line to the repeated delays to the Hinkley C nuclear reactor, why is the UK so bad at infrastructure projects?   This week, the Expert Factor team take a deep dive into what goes wrong when the UK wants to build big things. How did the costs for HS2 get so high? Is there the right level of government expertise to see through big infrastructure projects? Does the UK have a bigger NIMBY problem than other countries? And what could be done to learn from past mistakes?   A general election is looming. Manifestos are being drafted. The battle of ideas is intensifying. From tackling climate change to turning around the economy, rethinking Britain’s place in the world to restoring trust in politics, the UK is facing huge challenges. So how can we make sense of it all?    THE EXPERT FACTOR is the podcast for people who haven’t had enough of experts. Each week the directors of three leading and respected think tanks – Paul Johnson of the Institute for Fiscal Studies, Hannah White of the Institute for Government, and Anand Menon of UK in a Changing Europe – get together to discuss, debate and explain the big questions and themes that will shape the election – and the political landscape for years to come.    Producer by Milo Hynes and Podmasters.
