Question to the Home Office:

To ask His Majesty's Government what is their formal definition of extremism; and how they share this definition with police, local authorities, schools and others in order to measure the scale of extremism in British society and provide clarity to those bodies about their responsibilities and powers to intervene.

The current definition of extremism, which was last reviewed by the previous government in March 2024, is openly available on gov.uk. The definition is designed to support and shape policy, not data collection or operational activity.
