Jaguar Land Rover’s battle to recover from a devastating cyberattack could see its factories idle until November, according to suppliers briefed on the situation, raising fears of lasting damage to Britain’s largest carmaker and its supply chain. Suppliers are now reported to have been warned that assembly lines may remain dark for another seven weeks. Jaguar Land Rover denied issuing any official guidance to suppliers, insisting it was still working “around the clock” to restore its global IT systems in a “controlled and safe manner”. Thousands of staff remain on standby, with unions urging the government to consider a temporary furlough-style scheme to subsidise pay and protect livelihoods. For Britain’s wider automotive industry, the episode underscores both the risks of cyberattacks and the vulnerability of supply chains built on just-in-time production.
