In any family business, the occasional rift is bound to occur. With such close-knit units, familiarity can sometimes breed contempt.

But if you are going to have a feud, then at least do it properly! In Spain, control of 100-year-old Spanish biscuit firm Galletas Gullón, has just been wrested back by matriarch María Teresa Rodríguez from her three sons and two brothers. Having found herself locked out of company HQ, mama promptly called a board meeting in a Mercedes in the company car park. The meeting, convened with people allegedly controlling an 80% shareholding in the firm, saw Rodríguez appointed as sole administrator. But as the sons and brothers have refused to recognise the validity of the meeting, this particular dynastic saga could run and run.
