My hon. Friend makes an extremely important point. We knew already that the battle space is contested and that forces need to be closely integrated, but what Ukraine has shown above all else is the extraordinary extent to which electronic warfare plays a role. The mass jamming across the domain has to be factored into any kit that is used, and it will have to be factored into procurement going forward. We must be aware of these developments. We have our own brilliant resources, such as the Defence Science and Technology Laboratory, and there are things that we have done that are sensitive and that have provided support as far as possible, but he is right to talk in particular about the importance of the space domain. The UK is lucky to have a strong, sovereign space industry, supporting defence in the civil sector. Going forward, we need to be aware of how warfare is changing and be able to respond rapidly with our procurement.
