I thank the Secretary of State for that answer. As we mark the fourth anniversary of the illegal invasion of Ukraine, we salute the fortitude and bravery of the Ukrainian people. As we see conflicts open up elsewhere in the world, particularly the current situation in the middle east, how do we ensure that Ukraine continues to receive all the support it needs to determine its own future, and that the future of the Ukrainian people does not slip down the agenda, leading to another frozen conflict?

I would like to declare that I returned from Ukraine last week—I was part of a cross-party delegation—and my entry in the Register of Members' Financial Interests will be updated to reflect that. The newspapers and the television are this week full of pictures of people hunkering in bunkers in the middle east, but it is worth remembering that the people of Ukraine have been doing that for the past four years. The Foreign Secretary will of course be aware of the close relationship between Moscow and Tehran. Russia continues to deploy Iranian-manufactured Shahed drones to terrorise Ukraine's population. With the crisis in the middle east intensifying, will she set out how the Government now assess the implications of these recent developments for Russia's war in Ukraine?

Like the hon. Member for Tiverton and Minehead (Rachel Gilmour), I would like to note that my entry in the Register of Members' Financial Interests will be updated to reflect the support of the UK Friends of Ukraine for our visit last week. It was very good to see the Foreign Secretary in Kyiv last Tuesday for the very sad commemoration of the fourth year of the full-scale invasion. As the Ukrainian people have reminded us time and again, it is not just about territory; it is about their very identity. On our visit, we heard about the appalling inhumane treatment of Ukrainians who have been taken as prisoners of war by Putin. There have been constant violations of the Geneva conventions, including reports of torture and near starvation. What talks has the Foreign Secretary had and what more can she do to raise this issue in international circles and put pressure on the Russian regime to treat prisoners more humanely?

The Foreign Secretary mentioned the importance of Russian oil and gas and the need to disrupt the activities of the shadow fleet. Will she confirm that she is working with allies to ensure that as much as possible is being done to stop people using Russian oil and gas, because of how important it is to reduce the cash flows that are behind Russia's war effort?

As the Ukraine war passes its fourth year, we continue to salute the bravery and heroism of the people of Ukraine as they fight for their independence and freedom. This is the moment, however, for the Government to spearhead a new campaign with our allies to starve Russia of the funds it needs to wage war. It is clear that we need to target not only the shadow fleet but the refineries in Turkey, India and China buying Russian crude so that they rapidly diversify. Will the Government now take action with our allies to put huge new pressure on those refineries? With the foundations of the Russian economy crumbling away, that action would make it much harder for Putin to sustain the costs of his war.
