From the NHS Test and Trace Service to the lack of PPE at the start of the pandemic - both projects branded as having been incompetently delivered. But do we fail to notice the constraints their senior leadership team operate under? Evan Davis and expert guests discuss why some big public projects like the London 2012 Games went well. While others, like Crossrail, get bogged down in delays and a budget overspend. Just how is competence measured and delivered?

Guests:

Sir John Armitt, Chair of the National Infrastructure Commission, former Chair of the Olympic Delivery Authority
