Advisers urge JP Morgan investors to vote to split chair and CEO positions

SS and Glass Lewis back shareholder resolution amid fears over power wielded by Jamie Dimon, who holds both roles

Investors in JP Morgan have been urged to vote in favour of splitting the role of chief executive and chair at America's largest bank, amid concerns over the power wielded by its billionaire boss Jamie Dimon.

ISS and Glass Lewis, which issue advice to some of the world's biggest fund managers on how to vote at annual investor meetings, have thrown their weight behind a shareholder resolution that would ensure two separate people hold the office of chair and chief executive as soon as possible". Investors are due to vote on the resolution at the bank's annual general meeting on 19 May.
