Question to the HM Treasury:

To ask the Chancellor of the Exchequer, how many projects have left the portfolio in each year since NISTA began reporting because they were a) completed and b) cancelled; what the i) value and ii) cost of cancellation was of those projects; and what the lead department was for those projects.

In the 2025-26 financial year, 26 projects left the Government Major Projects Portfolio (GMPP) having successfully delivered their intended objectives, while seven projects left the portfolio following a decision to stop the project or bring it to an early closure. For further information on these projects, including project costs and lead departments, I refer the Hon. Member to the annual reports published to date by the National Infrastructure and Service Transformation Authority (NISTA):
