CEO Ivan Glasenberg added that COVID-19 had not changed the timing of succession plans, but declined to give further details.

"As we said as before COVID... once the old guard is changed then I will move on," he said, adding that the head of coal trading, Tor Peterson, was still due to leave. Long-time Glencore executive Daniel Mate, who led its zinc business, left last month.
