Whole Foods Market Inc. chief executive officer John Mackey has voluntarily relinquished his role as chairman of the group, according to a recent filing with the Securities and Exchange Commission in the US.

Mr Mackey, who has faced years of petitioning by an activist shareholder group to separate the roles of chairman and CEO, has held the position since the organic supermarket chain's inception in 1978, boston.com reported.

The group has said that lead director John Elstrott will take over the position of chairman, rendering his current position obsolete, while Mr Mackey remains on the board.
