Question to the Home Office:

To ask Her Majesty's Government what definition they use to establish which groups the police can reasonably label as domestic extremists; and which groups so labelled do not meet that definition.

The Government’s definition of extremism is set out in the 2015 Counter-Extremism Strategy. The strategy defines extremism as: ‘the vocal or active opposition to our fundamental values including democracy, the rule of law, individual liberty and the mutual respect and tolerance of different faiths and beliefs. We also regard calls for the death of members of our armed forces as extremist.’

There is no legal definition of extremism. It is an operational matter for the police what definitions they choose to use.
