Question to the Department for Transport:

To ask the Secretary of State for Transport, pursuant to the the Answer of 8 September 2025 to Question 71272 Lower Thames Crossing, for what reason no evaluation of the Lower Thames Crossing was completed prior to approval of the Full Business Case; and whether any interim assessments have been undertaken by (a) her Department and (b) the National Infrastructure and Service Transformation Authority.

The Full Business Case (FBC) for the scheme has not yet been developed. Decisions on the scheme remain subject to the Department’s established governance and assurance processes. These include rigorous internal scrutiny and oversight mechanisms, as well as engagement with external assurance bodies, including the National Infrastructure and Service Transformation Authority (NISTA).
