Sir John Allen Clark was managing director of the British Plessey Company, an electronics and telecommunications group built up by his father, Allen George Clark. His career with Plessey was dominated by a battle with Arnold Weinstock of GEC for control of the company together with English Electric from the 1960s. This culminated in the late 1980s with the takeover and break-up of Plessey.
