Carmaker Jaguar Land Rover (JLR) is reducing output at its factories in Solihull and Halewood until the spring, due to ongoing problems obtaining enough computer chips for new vehicles.
The action is expected to affect the output of models such as the Jaguar F-Pace and Land Rover Discovery Sport.
Output of these cars has been ramped up in recent months.
JLR's factory in Nitra, Slovakia, is not affected.
Modern cars are heavily reliant on computer chips to control a variety of onboard systems, ranging from anti-lock braking and emissions controls to satellite navigation and in-car entertainment.
But supplies from East Asia have been heavily disrupted in the wake of the Covid pandemic, while carmakers have faced intense competition for available supplies from other industries.
