Jamie Dimon. London Whale. JPMorgan Chase

John Gapper

My views on Jamie Dimon‘s dual roles as chairman and chief executive of JPMorgan Chase have not changed since a year ago, when I called for him to give up the chairmanship, but the stakes are much higher.

Mr Dimon faces a shareholder vote at the bank’s annual meeting next week to enforce a split of the two roles in the company bylaws. According to the Wall Street Journal, he has hinted that he might give up both jobs and leave if that passes.
