Question to the Department for Transport:

To ask the Secretary of State for Transport, will he publish the revised business case for Phase 1 of HS2 in the event that any of the Phase 2 lines are not built.

The next update of the business case for HS2 will be published prior to the authorisation of Notice to Proceed for Stage 2 (main construction) of the Main Work Civils Contracts, for Phase One.

As with previous business cases, this will show the value for money of each phase of the network as well as the ‘full Y’.

The Government remains committed to fulfilling its manifesto commitment to progressing High Speed 2. As set out in DfT’s Single Departmental Plan, the Government’s stated intention is to deliver the ‘full Y’ network.
