I thank the hon. Member for his response, and his bipartisan support on this really serious issue. What is NATO article 4? For clarity, article 4 is a consultation mechanism. If an ally perceives that its territorial integrity, political independence or security is threatened, it can invoke article 4. That is what Poland has done. Discussions will then take place in the North Atlantic Council, NATO’s senior political body, in which the UK will, of course, be involved.
I mentioned the status of the attacks. Poland stated that the drones were part of a co-ordinated Russian attack on targets across the border in Ukraine, but that does not in any way, shape or form excuse those attacks. They are an unprecedented violation of Polish airspace on an unprecedented scale.
I agree that our industrial collaboration with our allies and partners is essential, as we and NATO move forward, and as our partners and allies’ relationships move forward, to making sure that we are prepared in every way for an escalation, or an existential crisis, should it come.
In our response to Ukraine, we are doing a huge amount to lead our allies and partners. As we speak, the Secretary of State for Defence is with the E5, talking about the coalition of the willing, and he has talked to Polish representatives already. We are leading the way in that coalition—on its formation, structure and how it will deploy, should it need to, if peace ever comes to Ukraine.
