Why is the UK so bad at infrastructure?

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 – Paul Johnson of the Institute for Fiscal Studies, Hannah White of the Institute for Government, and Anand Menon of UK in a Changing Europe – 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?
