Latest jobsReports are emerging that former Yukos executive Vasily Alexanian, who is gravely ill with Aids and lymph cancer, is to be transferred from jail to a clinic.
The BBC quoted prison officials as saying Alexanian was set to be transferred. Alexanian is currently being tried in Moscow on charges of embezzlement.
The move to transfer him to hospital follows pressure from human rights activists on Russia's prison service.
It reverses a court ruling yesterday, which said that Alexanian should be treated in jail.
The Moscow court has suspended the trial, which began on Tuesday.
Alexanian, 36, is a former vice president of Yukos. He has been in detention since 2006 and denies all charges levelled against him, the BBC said.
His lawyers claim he has developed serious health complications and is nearly blind, while the European Court of Human Rights has repeatedly appealed for Alexanian to be treated in hospital.
Russia's human rights ombudsman Vladimir Lukin has also called for an independent medical examination of Alexanian.
The jailed Yukos founder, Mikhail Khodorkovsky, is on hunger strike in support of his deputy, and claims the case against Alexanian is politically motivated
Khodorkovsky is serving eight years in a Siberian prison after being convicted of fraud and tax evasion. He claims officials are punishing Alexanian for refusing to sign false confessions.
Yukos, once Russia's biggest oil company, was declared bankrupt in 2006 and ceased to exist as a legal entity in November 2007.
Yukos maintained it was the victim of a concerted political campaign by a government which wanted to discredit its executives and gain control of vital energy assets.
