There have been multiple reports of Ukrainian resistance and partisan activity in areas under Russian control, particularly in the south of the country. This has likely forced Russia to dedicate additional security personnel to areas it has occupied. Russia has deported 2.5 million people from Ukraine to Russia through filtration camps, and it has also likely detained and interrogated thousands of Ukrainians to try to quell the resistance. Such action will not deter Ukraine, and it will not deter the United Kingdom from continuing to support Ukraine in her fight.

I am not sure whether my hon. Friend has visited the sites, but I am delighted to have visited one of the sites twice. The first course completes this week, and it has been a learning experience for both sides. We will continue to invest in improving the course, and I am delighted that the international community has now joined us. The Dutch have declared that they will send people to support the training, and the New Zealanders were already here to help the Ukrainians on 105-mm artillery. We are talking with a number of other international partners about delivery.

Yes. One strength of NATO is its adherence to standards across all the nations in it. At the moment, Ukraine is transiting from using Soviet era calibres and so on to using western weapons systems, which is why it is important to help train Ukraine in their application; they are not one in, one out—they need to be used differently. Having helped establish the international donor co-ordination centre near Stuttgart, Britain has added training into that, so we co-ordinate that properly.

As we can see from our Conservative colleagues, defence spending is a key priority in the leadership race, and I recommend to all leadership candidates who are wanting votes from Conservative Members that they recognise its importance. The threat has changed and it warrants more spending on defence, because the world is more dangerous and anxious than it was—not only when we had the defence Command Paper but before Putin invaded.

With all due respect to the hon. Gentleman, I will not categorise it in six-month blocks. As long as I am Defence Secretary, we will continue with the investment and the support to Ukraine, be it in hardware or software.

I thank the hon. Gentleman for his constructive manner. We are learning as we go on the training, starting with a pledge to train 10,000 Ukrainian soldiers which may end up being 20,000 or more based on need. Our guided multiple launch rocket system is now active in Ukraine, delivering similar munitions that have had significant effects on Russian war capabilities. The key is to ensure Ukraine can withstand the summer and be prepared for winter.
