MOSCOW, October 7 (RIA Novosti) - A senator representing Russia's North Caucasus republic of Chechnya in the upper house of parliament has resigned, the Federation Council announced on Wednesday.
The chamber did not give reasons for Umar Dzhabrailov's resignation.
Dzhabrailov, 51, had been a member of the Federation Council since 2004 and deputy head of its international affairs committee, as well as a member of the Russian delegation to PACE. His term was to expire in 2011.
Dzhabrailov, president of Plaza Group and owner of the Danako chain of gasoline stations in Moscow, ran for Russian president in 2000.
He was accused of involvement in the murder of a U.S. businessman in 1996 and an assassination attempt on a deputy Moscow mayor in 2002. He denied both accusations, and his guilt was not proven.
Another Chechen lawmaker said on Wednesday that Dzhabrailov had quit the post in the Federation Council for a new "federal" job in Moscow.
