Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what comparative assessment his Department has made of the potential financial impact of index-linked government debt interest payments relative to baseline spending on core emergency and criminal justice services.

The Chancellor has been clear that fiscal discipline is his first priority. The fiscal rules keep debt on a sustainable path while allowing borrowing for investment.
