Russia's largest gold miner Polyus Gold (PLZL.MM) will list shares in London this summer, its main owner and chief executive Mikhail Prokhorov said late on Tuesday.

The London listing is a long-planned move to facilitate a merger with KazakhGold (KZGq.L).

Prokhorov, who took over as chief executive last year, told reporters he would stay on until he had completed two tasks: the London float and the sale of a strategic stake in the company that would put the company in the global top 5 gold miners.
