WBII today publishes a parliamentary briefing calling on the Government to proscribe the Muslim Brotherhood and the Islamic Revolutionary Guard Corps (IRGC) under section 3 of the Terrorism Act 2000. Our case is straightforward: Parliament already provided the legal tool; the evidential threshold is met; proscription will convert moral clarity into enforceable law across policing, prosecution, campuses, charities and broadcasting.
Why now
With Hamas defeated and the hostages home, the last excuse for ambiguity has gone. The enabling architecture remains—the IRGC’s state-directed network that exports violence and intimidation, and the Brotherhood’s ideological and organisational scaffolding that repeatedly blurs into terror. Proscription is not theatre: it criminalises inviting support, staging or addressing meetings to support, and displaying symbols that arouse reasonable suspicion of support, while tightening disruption of fundraising and mobilisation.
What the briefing covers
-
The statutory test and due-process safeguards (POAC appeals, affirmative procedure).
-
The operational gains of proscription: clearer charging pathways (TACT ss.11–13), firm bases for Prevent and charity governance, and practical support for councils and broadcasters to deny platforms that launder menace as “activism.”
-
A concise rebuttal of common objections, including claims about state organs and “engagement.”
What we’re asking
Lay the proscription orders for the IRGC and the Muslim Brotherhood, and align guidance so the law is not merely declared but used—calmly, evenly, and fast. Equal protection is the measure: the same standard that shields synagogues on Saturday shields mosques on Friday.
