When your business is about making products, and the factory you use gets into trouble, that’s potentially a big problem. Do you try to find another one, or do you try to fix it?

He also discusses the illness and personal loss that have shaped his career, and recalls his infamous appearance on Dragon’s Den almost 20 years ago.
