LONDON (Reuters) - David Crane, former chief executive of U.S power company NRG Energy, will exercise the voting rights for Russian bank VTB’s stake in EN+, as part of the agreement for the United States to waive sanctions against the company previously controlled by Oleg Deripaska, a source close to the matter said.

Russian tycoon Deripaska has agreed to reduce his stake in London-listed En+ to 44.95 percent from 70 percent and assign any voting rights above 35 percent to a voting trust formed by U.S. independent trustees D. J. Baker, David Crane, Arthur Dodge and Jersey-based Ogier Global Nominee Limited.

VTB Bank, Russia’s second-largest lender, lifted its stake in EN+ to 22.27 percent from 7.65 percent, as part of the deal, but will now have votes representing 6.25 percent that will be controlled by Crane.
