I'm afraid, for legal reasons, I can't comment on the content of the leak specifically, but I can comment on the consequences of it.
I think there's been a long process of building up trust with Ukraine, which has been very important in making sure that we provide the right support, because there are a lot of things that aren't necessarily as helpful as others. There can be no doubt that this will have restricted access to some of the information-sharing arrangements and potentially damaged that trust. That can be rebuilt, but it does add friction to things. There is very much goodwill on both sides to make sure that it doesn't cause problems, so I think it's not insurmountable. It just will add friction.
On the Russian side, what was exposed would certainly provide very useful information to the Russian military that it could use to try to counter what Ukraine is trying to do in its operations over the next few months.
Now, obviously, those slides relate to information that is earlier in the year. Some of those problems may have been resolved or, because of the dates outlined in them, the slides may no longer reflect the position, but certainly the shortage of air defence munitions, which has been widely discussed, is a very critical problem that has to be overcome. If the Russian air force can bomb from medium altitude, then that will inflict a very serious level of damage on Ukrainian forces, so making sure that this problem is overcome is now a critical priority.
