In the event that supply to MG Rover is terminated permanently, Wagon will restructure certain of its manufacturing operations in the UK, the maximum cost of which is expected to be approximately £1.5m.

"However, our first duty is to protect our own business and the interests of Wagon's shareholders, leaving us with no alternative but to pursue this course of action."
