A total of 340 jobs are under threat at the Honda plant in Swindon as the Japanese car maker announced it is to cut down production in the UK.
Honda said it will reduce production levels at the Wiltshire factory from three shifts to two to reflect weaker sales abroad.
There will also be a consolidation on to one line, the company added, to "improve production flexibility and efficiency".
Honda has had a plant in Swindon for 22 years and currently builds various models such as the Civic, Civic Tourer, and Jazz for the UK and European markets at the site.
Ian Howells, senior vice president of Honda Motor Europe, said: "Over the last 12 months, we haven't seen the growth we'd anticipated. With no increase forecast for the next couple of years, we must scale our manufacturing activity accordingly.
"However, with the restructuring we're taking today, and our new model plans, we remain confident in the long-term future of our Swindon plant. Our Swindon operation continues to be the hub for our European car manufacturing activity."
