Up to 500 jobs are to go at an automotive firm that supplies Jaguar Land Rover (JLR) from the car giant's former home on Brown's Lane.
Lawrence Automotive bought the site from JLR in 2010 and began supplying wood trim panelling for various models.
But according to Des Quinn, regional officer for the Unite union, promised investment in key areas by the Chinese owners never happened, placing the firm in "terminal decline".
He says the premises will close in November.
