Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what estimate her Department has made of the potential impact of the level of CPI inflation on the proposed change in tobacco duty on 1 October 2026.

The independent Office for Budget Responsibility (OBR) are responsible for estimating the impact of Government policies on inflation. The OBR did not include an assessment on the contribution of tobacco excise duty to inflation in the November 2025 Economic and Fiscal Outlook.
