Sir Julian Lewis: The main reason why this welcome uplift has come when it has is Russia’s aggression against Ukraine. Does the Secretary of State agree that if Russia and Putin are seen to fail in Ukraine, the threat to NATO will be put back for at least a generation? Conversely, if they succeed, the threat to NATO will intensify. Will he therefore do everything he can to persuade our allies, especially certain parts of the United States’ new political establishment, that the success of Ukraine is essential for the peace of Europe and, indeed, the peace of the world?

[The Secretary of State for Defence (Grant Shapps): My right hon. Friend is absolutely right. Although this is £75 billion and although it takes our budget to 2.5% of GDP, that is a fraction – a fraction – of what it would cost if Putin were successful in Ukraine. There is no chance he would stop there – none. Other autocrats elsewhere would look at that and exploit the idea that all they have to do is outwait the west and we will get bored of it – through some form of attention deficit – and give up defending the things we said we would never stop defending. That, in the end, would cost us all a huge amount more.]
