MOSCOW (AP) — A media company owned by Kremlin-friendly oligarch Alisher Usmanov has splashed out $1.5 billion to gain full control of Russia's most popular social network, VKontakte, bringing an end to a months-long dispute that saw the original investors sue each other in court. London-listed Mail.Ru Group said in a statement Tuesday that it now owns the whole of VKontakte following its purchase of a 48 percent stake from investment fund United Capital Partners. Mail.Ru's chief executive Dmitry Grishin lauded the deal, saying "the termination of all outstanding shareholder disputes will allow focus on the product and its further development."
