Russian President Dmitry Medvedev nominated Belykh for governor of the Kirov Region, in the northeast of European Russia, late on Monday. The current governor Nikolai Shaklein's term of office expires on January 14, 2009.
"I don't think I will be able to take part in the movement," Belykh said about the new Russian democratic movement, tentatively dubbed Solidarity, which has been proposed to protect the country's Constitution.
A number of opposition activists, including Garry Kasparov, leader of the United Civil Front, Yabloko party officials, Maxim Reznik and Ilya Yashin, as well as politicians Vladimir Milov and Boris Nemtsov, announced plans in early November to form the movement in response to Medvedev's proposal to amend the Constitution, extending presidential and parliamentary terms.
Yashin said: "If he becomes a governor, he will find it very hard to take part in a purely opposition project."
The Solidarity movement is expected to hold a founding congress on December 13.
