Jaguar Land Rover has said that employees at the Solihull plant will be working a three-day week until Christmas.
The car manufacturer said it planned to make “temporary adjustments to our production schedules”.
The carmaker said in a statement that it is standard business practice to “regularly reviews its production schedules to ensure market demand is balanced globally”.
“In light of the continuing headwinds impacting the car industry, we are making some temporary adjustments to our production schedules at Castle Bromwich,” it added.
“We are however continuing to over-proportionally invest in new products and technologies and are committed to our UK plants in which we have invested more than £4 billion since 2010 to future proof manufacturing technologies to deliver new models.”
The MP for Harwich and North Essex told BBC Radio 4’s Today programme: “I’m afraid I think he’s making it up. We’ve had figures made up all the time by the scaremongers in this debate, and I’m afraid nobody believes them.”
Last week, the carmaker’s boss Ralf Speth warned the government to get “the right Brexit” or risk big job cuts at the carmaker.
“Any friction at the border puts business at jeopardy,” he said.
“We are absolutely firmly committed to the UK, it’s our home. But a hard Brexit will cost Jaguar Land Rover more than £1.2 billion a year – it’s horrifying, wiping our profit, destroying investment in the autonomous, zero-emissions, we want to share.”
Jack Dromey, the Labour MP for Erdington, has described the carmaker’s changes at the Solihull plant as a result of Brexit. The MP wrote on Twitter that he blamed the “Brexit chaos and the mishandling by ministers of the transition from diesel”
