Keir Starmer's bold defence plans have been overshadowed by a row over money as he was warned Britain may not be moving quickly enough to counter the rapidly growing threats from countries such as Russia.
The prime minister vowed to make Britain "a battle-ready, armour-clad nation” as he unveiled his strategic defence review (SDR) at the Govan shipbuilding yard in Scotland, which included an army boosted to 100,000 personnel, 12 new submarines, drones and a rollout of Artificial Intelligence.
