Question to the Home Office:

To ask Her Majesty's Government whether they categorise antisocial or violent individuals by whether they are left wing or right wing; if so, why; and if so, what criteria they take into account when assessing whether any such individual should be described as left wing or right wing.

The Government takes seriously the threat from all forms of antisocial behaviour, extremism, and violence, including terrorism, whether this is motivated by left-wing, right-wing or Islamist ideology. Our response is however threat agnostic.
It is a matter for the Police to determine whether a crime has been committed and, where a crime has been committed, how it is classified. In its analysis of extremism, the Government applies the definition of extremism set out in the 2015 Counter-Extremism Strategy equally.
