A Russian court has rejected a parole plea by a business partner of jailed oil tycoon Mikhail Khodorkovsky.
The court in the northwestern town of Velsk said Wednesday that Platon Lebedev was not eligible for parole because of two breaches of prison rules, including the loss of a pair of trousers.
Lebedev, a board member of Khodorkovsky's oil company Yukos, has been in jail since 2003. Both men were arrested on charges of tax evasion widely seen as politically motivated and were convicted on those charges in 2005.
Lebedev and Khodorkovsky were tried together again last year and convicted of stealing oil from Yukos and embezzling the proceeds.
Lebedev was eligible for parole after serving half of his sentence.
