Question to the Department for Transport:

To ask the Secretary of State for Transport, pursuant to the Answer of 9 May 2016 to Question 36401, whether the Cabinet Secretary's involvement in the Infrastructure and Projects Authority's review of High Speed 2 was requested or authorised by a Minister; and what the membership is of the small cross-government team referred to in that Answer.

The Infrastructure and Projects Authority’s (IPA’s) support to the HS2 Programme is part of the normal assurance process for projects of this size, as mandated by Ministers. The Cabinet Secretary’s involvement is also normal for projects on the scale of HS2.

The IPA’s role on the Government's Major Projects Portfolio is to provide expertise in infrastructure and the financing, delivery and assurance of major projects, to support more effective management and delivery across government. The cross government assurance involves relevant experts from the Infrastructure and Projects Authority, the Department for Transport, HM Treasury and HS2 Ltd.
