Former military intelligence Сolonel Vladimir Kvachkov, once a suspect in an assassination attempt on Rusnano chief Anatoly Chubais, was sentenced Friday to 13 years in prison on charges of preparing a coup. Nationalist activist Kvachkov, 64, was arrested on Dec. 23, 2010, on suspicion of planning an armed revolt and involving people in terrorist activities. His arrest came one day after the Supreme Court found him not guilty in a 2005 attack on the cortege of Chubais, who at the time headed the Unified Energy System. "Judging by the way the verdict is written … it's Chubais' revenge," said Kvachkov's lawyer Oksana Mikhalkina after Friday's sentencing. Kvachkov has denied the charges. Kvachkov, smiling slightly, appeared calm as the judge read the verdict. Officers marched him away as soon as the trial adjourned, not giving him any time to talk to his wife or lawyers. His alleged co-conspirator, 62-year-old former police official Alexander Kiselyov, was also sentenced Friday, receiving 11 years behind bars.
