The appointment of a new independent non-executive Director will be announced in due course. The role of Senior Independent Director will be taken by Michael Lynch-Bell and Charles Watson became Chairman of the Health, Safety & Environment Committee in June 2013.

Simon Heale, non-executive Chairman of Kazakhmys PLC, said: "I should like to thank Phil for his many years of service and input to the Board and, in particular, the role he has played in developing the Group's health and safety culture. His background in industry and natural resources has been invaluable and his presence will be greatly missed."

Philip Aiken AM said: "I have had over six years of enjoyable and active involvement with Kazakhmys. Now that we have set a path for the disposal of our holding in ENRC PLC, having led and completed the recent process of the appointment of a new independent Chairman and given my commitments at other companies, I feel this is an appropriate time to retire from the Board. I wish Kazakhmys well in the future and will follow its development with interest."
