The Home Secretary will know that we have raised this many times. I understand the complexity of the issue. The proscribing legislation was drawn up more than 20 years ago to address terrorist threats such as al-Qaeda, rather than state-sponsored threats that have both domestic and international security objectives. Our bottom line must be keeping this country safe, which is why Labour has proposed new security legislation to allow the Government to put appropriately targeted proscription-style restrictions on the operations of state-linked organisations such as the IRGC. The Government previously resisted this, but will he look at it again in the light of recent events and work with us on any legislation that is needed to keep this country safe?
