Glencore is getting ready for an IPO that could be worth as much as $60bn (£37bn), although as City A.M. has revealed, a significant proportion of the shares could be issued by the Hong Kong stock exchange instead of being listed solely in London.

Its current chair, Stothotte, does not qualify because he was formerly chief executive of the company.
The Swiss commodities giant is understood to be in the process of short-listing candidates for a replacement alongside a general overhaul of its board.
