Labour has today stated its support for the proscription of the
  Islamic Revolutionary Guard Corps as a terrorist organisation,
  either through the existing proscription process or through an
  amendment to the National Security Bill that would create a
  parallel power to proscribe state bodies like the IRGC on the
  basis of their activity.
  It follows the growing threat that the IRGC poses on UK soil, as
  well as in response to the crackdown on protestors,
  the unjust imprisonment of British
  nationals in Iran, the execution
  of Alireza
  Akbari, long-standing concerns about Iran’s threats
  to Israel, and its support for violent groups across the region.
  In his most recent threat update, MI5 Director Ken McCallum
  referred to 10 kidnap and death plots by the Iranian regime on
  British soil. Yesterday, British-Iranian Alireza Akbari was
  barbarically executed.
  Labour’s Shadow Foreign Secretary,  MP, and Labour’s Shadow Home
  Secretary,  MP, said:
  “The Iranian Regime’s actions against courageous protestors
  seeking a better future, as well as British nationals imprisoned
  in Iran and its threats to UK security mean robust action is
  needed now.
  “The IRGC is behaving like a terrorist organisation and must now
  be proscribed as such. Labour supports proscribing the IRGC
  either through the existing process, or through amending the
  national security bill to create a new process of proscription
  for hostile state actors.
  “Labour will always take the actions necessary to keep the
  British public safe.”

  Notes
  - Proscription would provide enforcement agencies with stronger
  powers to disrupt the IRGC’s activities in the UK, and to keep
  people safe. This could either be done by proscribing the IRGC as
  a terrorist organisation under the existing Terrorism Act 2000.
  Or, in order to keep the existing regime solely for non-state
  groups like Al Qaeda, the government could amend the National
  Security Bill to create a parallel power to proscribe state
  bodies like the IRGC on the basis of their activity. Labour is
  urging the Government to come forward with amendments to the
  National Security Bill to tackle hostile state terror activity if
  existing counter-terrorism powers are not sufficient or specific
  enough to tackle the IRGC.
  
 
  - The Independent Reviewer of Terrorism Legislation, Jonathan
  Hall, has suggested this approach - arguing that “In principle
  the National Security Bill could contain a power to proscribe
  state bodies on the basis of their hostile activity, but does
  not.”
