Land Rover has announced it will cease production of the Discovery SUV at its Solihull assembly plant in 2019.
The carmaker will move all Discovery production to Slovakia, and said some jobs in the UK will be at risk.
It said it remains "committed to the UK" and the Solihull plant will build a new Range Rover model.
"The potential losses of some agency employed staff in the UK is a tough one but forms part of our long-term manufacturing strategy as we transform our business globally," said parent Jaguar Land Rover.
There are 1,800 agency workers in the Solihull plant, out of a workforce of 10,000.
Previously, JLR had said the manufacture of the Discovery would be split between Solihull and Slovakia.
