Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, what steps she is taking to ensure the accuracy of data used by her Department, in the context of the letter entitled Statements on Water Quality by Professor Dame Carol Propper, Chair of the UK Statistics Authority published on 28 October 2025.

The accuracy of data and statistics are crucial for the development and monitoring of Defra policies, and crucial for ensuring public trust in those statistics. All Official Statistics in Defra are therefore produced in line with the UK Statistics Authority’s Code of Practice for Statistics.
