Question to the Department for Transport:

To ask His Majesty's Government why advice from the Infrastructure and Projects Authority that "The project (HS2) will remain fundamentally flawed unless transparency and frankness is provided to the true level of uncertainty and confidence variations of time, cost and benefits", as reported in the Sunday Times on 22 October, was not provided to Parliament before it approved authorisation for Phase 1 of HS2

On 11 February 2020, the then Prime Minister announced that the Government intended to proceed with HS2. This decision was made having considered the conclusions of the Independent Review of HS2, led by Douglas Oakervee, and an accounting officer assessment that demonstrated the ongoing compliance of the programme with HM Treasury managing public money guidance. This assessment followed four previous assessments undertaken at regular intervals in 2019.

Since the HS2 Phase 1 Notice-to-Proceed decision, comprehensive governance arrangements have been put in place to increase Ministerial oversight, transparency, and accountability of the HS2 project. Since October 2020, the Department has published six-monthly reports to Parliament, while the Infrastructure and Projects Authority’s Annual Report includes assessments on HS2. HS2 Ltd is held to account in several ways, including through a monthly Sponsor Board meeting that oversees the company’s performance and reviews the latest Management Information. HS2 Ltd’s Board was also strengthened with new Non-Executive Directors, including a representative from the Department for Transport.

The National Audit Office has published multiple reports examining the delivery of HS2, and the programme is scrutinised by Parliament on a regular basis.
