The Commons public accounts committee has issued a withering assessment of the HS2 high-speed rail project, warning costs were spiralling whilst benefits were dwindling.
The committee said the case for the £50 billion project was based on "fragile numbers, out-of-date data and assumptions which do not reflect real life" with no evidence it would aid regional economies not simply "suck" even more activity into London.
It has demanded an urgent explanation of how quickly the Department of Transport could plug the "significant" gaps in the commercial and major project expertise in its teams.
