A judge jailed a Russian scientist for 15 years today for spying for the West, Russian news agencies said, in a case denounced by rights activists and his lawyers as unfair and rigged.
Igor Sutyagin, a nuclear weapons expert, was convicted of treason by a jury on Monday after being found guilty of passing classified military information to a British firm alleged to be a front for the US Central Intelligence Agency.
Sutyagin, denying spying, had said he wrote an analysis based on information that was in the public domain.
He has 10 days to appeal against the sentence in the Supreme Court. Interfax news agency said the court had ruled his jail term would run from October 1999 when he was arrested.
The prosecution had sought a 17-year sentence for 39-year-old Sutyagin, close to the maximum for treason.
Trial by jury was introduced in post-Soviet Russia only two years ago and many rights and legal experts doubt it operates freely as President Vladimir Putin embarks on a second term.
Sutyagin's defence said yesterday that the 12-member jury had come under pressure and had been badly directed by the judge who had ignored the key defence argument - that information disclosed by Sutyagin was publicly available.
All 12 jurors found him guilty of passing on classified information on fighter aircraft and nuclear-powered submarines to the firm, Alternative Futures, alleged to be a CIA front.
Human Rights Watch said that Russia's FSB domestic intelligence agency had pressed hard for Sutyagin's conviction after the acquittal last December of scientist Mr Valentin Danilov.
Mr Danilov was cleared of spying for China, an outcome that prompted many senior officials in the FSB to question the competence of juries to handle such cases.
