Russia's assault on Ukraine is unprovoked, premeditated, barbaric and an assault on a sovereign democracy. The UK has committed £220 million of humanitarian assistance to Ukraine and the region. We are in regular contact with our allies across the world, as well as international agencies such as the UN and other humanitarian partners and donors, to assess the needs on the ground and to ensure an internationally co-ordinated response. We call on Russia to respect its obligations under international humanitarian law.

We note Russia's claim of creating humanitarian corridors. These are just not credible. The current humanitarian corridors that Russia has highlighted lead into Russia, and it is an obscene and offensive gesture to the Ukrainian people to invite them to take refuge in the arms of the country currently seeking to destroy theirs. It is not credible and we call upon Russia to allow proper, meaningful humanitarian access.

As my right hon. Friend the Foreign Secretary said, the Home Office has established a forward presence, including just over the Ukrainian border into Poland, in order to facilitate cases like the one that the hon. Lady has raised. We continue working closely with the Home Office to ensure that its work on receiving Ukrainian refugees is as quick, effective and efficient as possible.

The hon. and gallant Gentleman raises an incredibly important point. Our ability to project influence into Ukraine is understandably heavily curtailed. We will continue working to ensure that potential human rights abuses are catalogued and put forward for subsequent trials in the International Criminal Court and other places, if relevant. I take the point about what more can be done to help the brave people who have stayed behind to do great work in Ukraine and what we can do to help them to evacuate the country. I cannot give him details at the moment but his point is well made.

My hon. Friend raises a very important point. As we have said, the Home Office has established a forward presence in Poland, but also in the other countries bordering Ukraine, to facilitate the forward passage for those wishing to come to the UK. The Prime Minister and the Home Secretary have made it clear that we intend to have a generous offer to the Ukrainian people of refuge to those seeking that, and we will continue co-ordinating with the Home Office in its work to establish routes to the UK.

The UK should be rightly proud of the support that we gave to the Ukrainian armed forces over a number of years through Operation Orbital and through the early deployment of NLAWs—the anti-tank missile systems that have proven so effective—and we will continue to provide support to the Ukrainians in their self-defence. The Secretary-General of NATO has made it very clear that it would be wrong for NATO to engage directly in the conflict with Russia that is the inevitable by-product of a no-fly zone. Putin is desperately trying to paint this as western aggression against Russia. We must not do anything that will allow him to perpetrate that perverse distortion of reality.

We take attacks, or the threat of attacks, against nuclear facilities very seriously. Nuclear safeguarding remains a priority for this Government. I will not be drawn on the conditions of what might be defined as an attack on NATO, but nevertheless we have made it absolutely clear that NATO is a defensive organisation. It has never expanded by force or coercion. Our support to the Ukrainians is steadfast, but there is a clear dividing line between an attack on one of our good friends—Ukraine—and an attack on a NATO member state.

The situation is rapidly evolving. We have announced significant humanitarian support, the largest in the world at this stage. We are more than happy to keep the House up to date with the disbursal of that humanitarian aid through normal means.
