The Brooklyn Nets’ billionaire owner probably has lots of business endeavors he could spend his time tending to, but the NY Post reports he’ll be leaving those aside to focus full-time on his political career. No word on what that means for his interest in the Nets… More details, via the Post: “Billionaire Brooklyn Nets owner and former Russian presidential candidate Mikhail Prokhorov said Saturday he’s leaving business to focus full-time on politics, returning to the political arena after remaining silent through a five-month Kremlin crackdown on the opposition. The 47-year-old Prokhorov, who is believed to be worth about $13 billion, finished third in Russia’s presidential election in March amid speculation that his candidacy was orchestrated by the Kremlin. Though he denied the claim, he was nowhere to be seen as the government launched a crackdown on the opposition this spring, arresting activists and introducing new harsh legislation. Prokhorov appeared Saturday at the first conference of the party he set up several months ago, announcing that he would put his money in a trust fund and let his partners at the investment vehicle Onexim run the shop.”
