Question to the Department for Transport:

To ask the Secretary of State for Transport, pursuant to the answer given 17 November 2025 (UIN 88239), if she will publish the evidence provided to her in relation to the A12 Widening Scheme by (a) the Ministry for Housing, Communities and Local Government and (b) other agencies to inform her decision to cancel the A12 Widening Scheme.

The evidence provided to the Secretary of State for Transport in relation to the A12 Widening Scheme by (a) the Ministry for Housing, Communities and Local Government and (b) other agencies, formed part of a much larger body of evidence that informed the Spending Review and subsequent decisions.

There are no plans to publish officials’ advice and evidence base to Ministers that informed the Spending Review and subsequent decisions, as has been the usual practice of successive administrations, including the one the Rt Hon Lady served in.

Detailed information on the analysis of the A12 widening scheme, conducted in accordance with the HM Treasury Green Book and the Department’s Transport Analysis Guidance, was published on the Planning Inspectorate’s website, available here: https://national-infrastructure-consenting.planninginspectorate.gov.uk/projects/TR010060.
