Chris Griffith, the CEO of Vedanta Base Metals, has resigned from the mining firm recently.
Vedanta Group is facing criticism from US short-seller Viceroy Research, who released a report shorting the debt held by Vedanta Resources.
Griffith's departure comes amidst concerns over Vedanta Resources' debt burden and its group structure.
Vedanta dismissed Viceroy Research's report as containing 'selective misinformation and baseless allegations' and emphasized their focus on business growth.
