I am grateful to both Front Benches for their questions, and I will try to answer them as best as I can.
To summarise for the House, colleagues will know that on Saturday 3 May counterterrorism police undertook a series of arrests relating to what I must make clear are two separate incidents and investigations, and a total of eight men were arrested by the Metropolitan Police Counter Terrorism Command under counter- terrorism and national security legislation. I can update the House to confirm that seven of those eight men currently remain in custody, and one is on bail with extremely serious and tight conditions. These are the first Iranian nationals arrested under the National Security Act. I join in the tribute that has been paid to the police and the security services, who have managed this event and brought the issues to conclusions on 3 May.
However, as colleagues have mentioned, this is an ongoing investigation so I am limited in what I can say and comment upon, but I want to say first and foremost that it is important that we hold Iran to account. Both the noble Lord and the noble Baroness asked what the Government can do to hold Iran to account. Noble Lords will recall that earlier this year, we announced in both Houses of Parliament the Foreign Influence Registration Scheme. It comes into effect on 1 July and ensures that a number of individuals connected with Iran, one of the first countries designated under the scheme, have to register a number of matters under that scheme by 1 July.
As the noble Baroness has mentioned, we have sanctioned a number of criminal entities that Tehran uses to do its bidding, such as the Foxtrot network—related documents will come before both Houses—alongside more than 450 Iranian individuals and entities that have been sanctioned to date by the UK Government.
Both Front Benches have mentioned proscription. It is common knowledge that we keep that under constant review. We have asked Jonathan Hall KC to provide a view on the counterterror framework, which does not fit neatly with existing states to date, and the Home Secretary has asked him to lead a review. I can confirm to the House today that that review has been finalised. We will be publishing it and its response shortly for colleagues in both Houses to examine, and we will make further announcements in due course on those issues.
It has been asked what steps we have taken on international engagement, whether we have consulted our allies and whether the Foreign Office had summoned the Iranian ambassador. In the Statement, we have said that the investigation is still in its early stages and the police are following various lines of inquiry as to the possible motivation of those currently arrested and in custody, or on police bail. I assure the House that as the investigation progresses, I will both engage internationally as appropriate and report back to the House on the issues that have been raised.
We are stronger when we are united, and our allies were supportive of the action over the weekend when this news broke. I know that the Foreign Office and the Foreign Secretary have reached out to key international partners to discuss those events with them.
We have judged sanctions to be a vital tool in deterring and disrupting Iran’s malign activity. They demonstrate that, along with our international partners, the UK continues to condemn Iran’s threats to international security and its human rights violations. We will be exploring further sanctions against Iranian-linked criminals, and the National Crime Agency will particularly target those who assist the IRGC and others in laundering their money.
The noble Baroness mentioned the overseas aid budget. There are some difficult decisions that the Government are taking. We have not yet finalised it; I have been in discussions with Ministers in the Foreign Office about that as it impacts upon areas of Home Office responsibility, but those issues are not yet finalised. Again, unfortunately, I cannot give any further detail to the noble Baroness at this point.
Both Front-Benchers mentioned that it is important that we ensure that individuals who are under threat are protected. Members of the House will know that the Home Office has worked with other government departments, as well as with relevant government agencies, to protect those identified as being at risk. The police and security services, as well as tracking down potential plots and threats, are working tirelessly to take other steps to ensure the safety of those concerned. Noble Lords will know that the Government have a general scheme for places of worship, particularly in relation to members of the Jewish community and synagogues. We have significant resource invested in protecting diplomatic missions, places of worship and individuals’ right to practise their religion at their chosen place of worship.
I cannot give details, and I am grateful that colleagues have not asked for further information, on the possible target, because it is an ongoing operation. I hope I can reassure the House by saying that the police have confirmed that they are in contact with the site that was the potential target. They have offered support, they have provided further security and other relevant advice, and, at the appropriate time, when it is safe to do so, the police will, and I will, through this House, confirm the alleged target of this plot. The Home Secretary has given a commitment to update both Houses—herself and the Security Minister in the other place and via me in this House—when it is operationally possible to do so. We will review state threats and the proscription tool as a matter of some urgency, and I hope I will be reporting on what Jonathan Hall has said and recommended to the Government, and our response to that, very shortly.
This is an ongoing investigation. When further information comes to light, the Government will bring it to both Houses. I felt it was important, following the incidents and arrests on 3 May, to make an early Statement, however general that is, to update the House on an important disruptive element identified by the security services, who I reserve absolute praise for in their tracking and taking action to prevent this alleged incident. The House will, in due course, be further notified of the contents of that incident.
