(Reuters) - Chevron Corp Chief Executive John Watson is stepping down from his post atop the nation's second-largest oil company, according to a report from the Wall Street Journal.
A successor for Watson, 60, who has been the company's chairman and chief executive since 2010, has not been formally approved by the company's board. A leading candidate is Michael Wirth, 56, Chevron's vice chairman, the WSJ said.
Chevron spokespeople were unavailable to comment immediately.
