Podcast host Duncan Barkes is joined by TPA researcher Callum McGoldrick as the TPA launches a new report: Big Spending Projects Gone Wrong.

They also talk to HS2 campaigner Michael Gross about his campaign: Where's The Money?  

The TPA is calling for robust forecasting, an expanded Nationally Significant Infrastructure Projects framework, penalties for failing project leaders to protect taxpayers and for politicians to bring major projects under greater ministerial control.
