Britain bets big on AI to defend against the threats AI is helping create

The UK government is throwing £130 million at AI-powered cyber defenses, including plans to deploy autonomous AI agents across critical infrastructure to hunt down security flaws before attackers get there first. The money is part of a wider £600 million-plus AI spending spree announced by the Treasury ahead of this week's Budget, with ministers also promising to tackle biological threats, bankroll British AI firms, and reduce the country's dependence on foreign technology.
