Sir Robert Horton: Dynamic and combative head of BP and Railtrack

Sir Robert Horton had a forceful, dynamic management style which in 1990 propelled him to the top of British Petroleum, then the world's third-largest oil company. It was assumed he would develop into a titan of the industry. But his trademark vigour was accompanied by another trademark, that of imperious arrogance, which despite his undoubted talents led to his removal as chairman and chief executive within two years.
