Copper miner Kazakhmys has reportedly singled out Philip Aiken as its favoured candidate to replace Vladimir Kim as chairman. Aiken, who has been a non-exec at the FTSE 100 company since 2006, is also on the board at recruiter Robert Walters, energy firm Essar and National Grid. Kazakhmys has hired headhunters in recent weeks, after top shareholder Kim said that in May he would step down to make way for an independent chairman. Kazakhmys, part-owned by the Kazakh government, is one of several foreign-owned, London-listed miners to have come under scrutiny in the past year over corporate governance rules and the protection of minority investors. Kazakhmys declined to comment yesterday.
