Reuters A delay in allowing billionaire tycoon Mikhail Prokhorov's gold firm Polyus to sail into the prestigious FTSE 100 Index, while probably procedural, leaves nagging concerns that politics and business in Russia make for a dangerous cocktail. The postponement, ordered by a committee chaired by Prime Minister Vladimir Putin, comes just two months after Prokhorov's sudden exit from Russian politics following an acrimonious clash with the Kremlin. In his brief foray into politics, Prokhorov had hoped to lead a liberal party that enjoyed official backing into December's parliamentary election, but his autonomy and ambition unnerved Russia's leaders and he was abruptly ousted. Putin's announcement that he will run for a third term as president in 2012 has reinforced concerns amongst Russia's super rich that they own their assets at the pleasure of the country's rulers. Prokhorov's fortune has been estimated at $18 billion by Forbes magazine. “The power is such that nothing is really safe,” said one industry source. Officials have given assurances that the delay to allowing Polyus , Russia's largest pure-play gold miner, to list in London was purely technical. “There were no political reasons there and could not have been. The matter required additional work because certain documents were lacking,” said Putin's spokesman, Dmitry Peskov. But no date has yet been set for the next meeting of the committee, which has a sweeping mandate to rule on issues concerning the foreign ownership of strategic assets in Russia. And memories remain fresh of the fate of Mikhail Khodorkovsky, who was jailed for fraud and tax evasion in 2005 and lost his $40 billion oil empire after mounting a political challenge to Putin. Khodorkovsky remains in jail. Political ties, however, have not proven universally problematic. “Polyus has had a colorful history — but a lot of other companies have in the past and that hasn't stopped them being listed,” said Roland Nash, chief strategist at hedge fund Verno Capital in Moscow. Robert Mantse, mining analyst at Otkritie bank in Moscow, said Polyus' premium London listing was a question of “not if, but when”. While Britain's relationship with Russia has been rocky in recent years, London's draw is more powerful than ever for Russian businessmen who seek capital, prestige and a haven from the rough and tumble of their home country's business world. “When you're worth $10 billion you are probably less focused on getting to the next $20 billion — you're probably thinking: ‘How do I preserve what I have?'” said one senior banker. “You would naturally take all steps to diversify your wealth and your exposure away from one geography that you know is going to be volatile, at least for the next generation.” A holdup for Polyus could allow two rival Russian miners to beat it to coveted spots in the FTSE 100 index, gaining access to a wider pool of investors and creating an acquisition currency just as the sector undergoes global consolidation. __
