A failure to obtain Russian regulatory approval caused gold miner OAO Polyus Gold on Tuesday to delay plans to gain a listing on the London Stock Exchange.

Russia's Government Commission on Monitoring Foreign Investment in the Russian Federation has postponed its approval for the listing of the company, which is owned by billionaires Suleiman Kerimov and Mikahail Prokhorov.

Polyus still plans an extraordinary general meeting Friday to approve the plans, which involve setting up a Jersey-based holding company that would then list on the London Stock Exchange.

The plan would still require approval of the Russian regulator.
