Question to the Department for Transport:

To ask His Majesty's Government what is the latest estimated cost of the construction of the HS2 tunnels from Old Oak Common to Euston.

The Government has confirmed its committed to delivering HS2 between Birmingham and Euston at the recent budget. The scope of Phase 1 is being reviewed to ensure the HS2 scheme is delivered at the lowest reasonable cost, including the revised approach to Euston. Once this work has been done, we will publish to Parliament a revised cost range for the revised HS2 scheme including the cost of the tunnels from Old Oak Common to Euston.
