With your forbearance, Mr Speaker, may I join the expression that you gave on the fifth anniversary of the murder of PC Palmer? I send my sympathies to the family and our total solidarity in this House with those who risk their lives on the frontline. Vladimir Putin's regime is responsible for an illegal invasion. There is strong evidence of war crimes and we believe that those responsible must be held to account.

We are doing two things in particular. First, I have convened a cross-Whitehall group, which we have done in the past, to ensure that we can provide whatever support may be needed for everything from witness protection services to the gathering of evidence and information co-operation. Secondly, I have been to The Hague and I will be going back this week. I am working with a coalition of countries that also have unique expertise in that area to provide the support that the Court needs.

My hon. Friend will know that, because of the Sergei Magnitsky regime for asset freezes and visa bans for anyone who has committed serious human rights abuses, we already have that capacity in place. That is on top of the further co-operation that we will provide with the ICC and, I should mention, that the Attorney General will provide with the prosecutor general of Ukraine.

My right hon. Friend is absolutely right. I am always careful to allow the ICC, of which both the prosecutor and the chambers of the Court are independent, to make those determinations, but the points of principle that he has set out are absolutely right. There must be no impunity for those in Moscow or the commanders on the ground who commit those atrocities.

My hon. Friend is right. We secured the election of Karim Khan and Jo Korner. They operate independently on the Court but it is a sign of how well regarded this country's legal profession is that we have two such senior figures there, as well as the registrar. Again, they operate independently, but we are working with the Ukrainian authorities, led by the Attorney General. I am also going back to The Hague to ensure that we understand the specific needs of the ICC, not just to provide support ourselves but to ensure that we bring together a coalition of countries with that unique expertise so that justice can be done.

My hon. Friend is right, although, of course, we have a war going on and we need to be realistic that that will take time and strategic patience. We had Radovan Karadžić, the butcher of the Balkans, delivered to a British jail cell last year under a sentence enforcement agreement that I happened to negotiate with the UN in 2004. These things will take time; that is the realpolitik that we are dealing with. We are ensuring, however, first, that things such as the preservation of evidence are a priority now in conduct on the ground, and secondly, that the message goes out that we and our partners in support of the ICC are being clear that, if someone commits those kinds of crimes, sooner or later they will end up in the dock of the Court and behind bars.

The hon. Gentleman is absolutely right, and I thank him for what he has said. I would be happy to update the House through oral questions or other means, and I am very happy to meet him. It is absolutely right that there will not be a peaceful settlement to this. I think we can all agree that trusting Vladimir Putin to keep his word is going to be a very tall order for anyone in the community, let alone President Zelensky, and there cannot just be a brushing under the carpet of atrocities committed now or in the future.

I thank the hon. Gentleman, who makes a really important point. Of course, I must at this point say that it will be for the ICC, which operates independently, to determine the temporal scope of its jurisdiction.

The hon. Gentleman is right that we are looking at ways to support independent media sources so that Russians get the facts on the ground about potential accountability before the International Criminal Court. We are also considering how conscripts and commanders could be at risk under this accountability framework.

The hon. Gentleman is correct that one of the critical issues right now is preserving early evidence regarding orders from higher command and committing crimes. We are looking at ways to work with our allies, leveraging unique capabilities in law enforcement such as information cooperation, witness protection, sentence enforcement, and forensic evidence.
