Prime Minister Sir Keir Starmer has pledged to "mobilise the nation" as he announced his defence review, claiming a "new era" for the country's national security.

Speaking from Glasgow, Starmer declared: "The Strategic Defence Review that I'm launching today will bring that unity of purpose to the whole of the United Kingdom, to mobilise the nation in a common cause, recognising in these dangerous times when it comes to defence of the realm and the defence of everything that we hold dear.

"Every part of society, every citizen of this country has a role to play, because we have to recognise that things have changed in the world of today. The threat we now face is more serious, more immediate, and more unpredictable than at any time since the Cold War.
