Jaguar Land Rover has confirmed it is cutting back production at its Castle Bromwich plant in Birmingham because of falling car sales.
No cars were produced at the plant for four weeks over Christmas and another two weeks of shutdowns are planned.
The company blamed falling sales in the UK - caused by a lack of consumer confidence over Brexit and worries over diesel cars.
There are no plans to cut production at its Solihull plant or the engine factory in Wolverhampton.
It has cut production at its plant on Merseyside.
