Shareholders of US supermarket firm Kroger Co are to vote on a proposal that would prevent the company’s chairman from also holding the position of company chief executive.

The proposal, which is opposed by Kroger’s directors, is to be included at the annual meeting of 24 June, when shareholders will be able to vote on the issue, reported the Associated Press.

The vote was proposed by the United Association S&P 500 Index Fund, which said the proposal is aimed at making the board and its directors more independent.
