Question to the Department for Transport:

To ask the Secretary of State for Transport, pursuant to the Written Statement of 23 February 2026 on Update on disclosed documents for AC-2025-LON-003837, which official was responsible for the incorrect application of fuel efficiency measures within the Department’s Aviation Model; and what grade that official was.

The Department does not name individual members of staff. Such updates are always quality assured, which involves checks from various analysts who are not directly involved in the work. The Department’s quality assurance processes are fully aligned with the Government’s AQuA Book (the quality assurance guidance), but I have asked my officials to strengthen our practices further.
