To ask the Chancellor of the Exchequer, with reference to page 41 of her Department's document entitled Autumn Budget 2024, Policy Costings, published on 30 October 2024, what the evidential basis is for the Exchequer impact of changes to agricultural property relief and business property relief being £495 million in 2027-28; and what the split is between the two reliefs.

The costing methodology for reforming agricultural property relief and business property relief from 6 April 2026 by maintaining 100% relief for the first £1m of combined assets and 50% relief thereafter, and 50% relief for “not listed” shares on the markets of a recognised stock exchange is published in the Autumn Budget 2024 Policy Costing Document on page 41:
