Supermarket denies boss moving to F1 8 April, 2013 Justin King Sainsbury’s, the UK supermarket giant, has denied reports it could lose its boss to Formula 1. Last week, Formula 1 chief executive Bernie Ecclestone failed to deny rumours Sainsbury’s Justin King is being lined up to replace him. “I’ve no idea whether the boss of a company like Sainsbury’s could do my job,” the 82-year-old told the Guardian. “Maybe he could.” A Sainsbury’s spokesman has now replied: “This is pure speculation. “Justin’s made his commitment to the business clear and is excited about Sainsbury’s long-term prospects for growth. Any discussion of succession is entirely premature.” Notably this story broke on April Fool’s day.
