Philip Hammond to spend extra £1.9bn fighting cyber-attacks

Growing online threat putting national and personal security at risk, says chancellor

Outdated computer systems are allowing malicious hackers to target everyone from companies at board level to individuals in their living rooms, according to the chancellor, who is promising to strike back against cyber-attacks.

Philip Hammond will use a speech on Tuesday to unveil a 1.9bn package designed to boost Britain's defences against a growing online threat, which he will say is invading personal privacy and putting national security at risk.
