“But we have also seen the Nato alliance come together like never before in support of Ukraine and with firm determination that Russia cannot succeed.

“That is work we need to continue this week. We cannot let the fog of war obscure the clear lessons our alliance must learn if we are going to outpace and outmanoeuvre those who seek to do us harm.

“That is why the UK is investing record amounts in defence, to make our Armed Forces more lethal and more deployable, and to ready our defence industry for the challenges ahead. And that’s something we need to see across Nato, starting with meeting the two percent commitment.”

The PM’s spokesman added: “He will call for all allies to immediately meet the ambition they set almost two decades ago – to spend two percent of their GDP on defence. Our reinforced alliance can then further harden its deterrence and defence, building on the decisions we have made in the wake of Russia’s full-scale invasion to accelerate Nato’s military transformation. The UK will lead these efforts, just as we have throughout the history of the alliance.”

“If the war is going on, then we’re all at war. We’re at war with Russia, if that were the case.

“I think we have to lay out a rational path for Ukraine to be able to qualify to be able to get into Nato.”
