Sir Julian Lewis: May I commend to anyone interested in the historical context a report produced by the Defence Committee in July in 2019 called, “Shifting the Goalposts? Defence Expenditure and the 2% Pledge: An Update”, HC 2527? It shows that for the last 20 years of the cold war this country spent between 5.6% and 4.1% of GDP, calculated in the same way we do today, on defence. Does that not show both sides of the House that we have an awful long way to go now that there is a hot war in Europe before we match what we used to do when there was a cold war in Europe?

[The Minister for Defence Procurement (James Cartlidge): My right hon. Friend put that eloquently, and he speaks with great passion and expertise on the cold war and our recent history. As he knows, in the cold war era we had the working assumption that an invasion – or certainly a confrontation – could be launched on the border in Germany very quickly. We had a huge number of forces deployed, and given that threat we spent, understandably, a higher percentage of GDP on defence. Since then, we thought we had a more peaceful era. Those illusions have been shattered by Putin, and we have all had to wake up to that. That is why we have done so much to support Ukraine and, yes, why we will do everything possible to support our armed forces.]
