Alexei Navalny has left the IK-2 concentration camp where he has been in recent weeks and has now been moved to an unknown location.
Russia's Federal Prison Authority states that information about his whereabouts cannot be disclosed, citing privacy laws.
Skip release
In January this year, Navalny was given a suspended sentence of just over two and a half years in prison.
At the same time, his movement states that there is hope of being able to get him released earlier than that.
Chief of Staff Leonid Volkov tells SVT's Agenda that the movement has now focused all work towards getting Navalny released.
- We are not ready to accept that he will be in prison for several more years.
We believe that a lot can be done to get him out faster, he says.
The movement organizes demonstrations and coordinates international actors to put pressure on Russia, Volkov says.
Great support
The international support for Navalny is great.
Just two days ago, 45 countries urged Russia to release the regime critic.
A statement read out at the UN Human Rights Council in Geneva called for the release of Navalny and the investigation into last year's poisoning.
The signatories were mainly European countries, but the USA, Canada, Australia and Japan have also signed.
Although Navalny will remain in prison in the coming years, the movement states that it is prepared to continue conducting active opposition work.
- We continued to work when he spent a year under house arrest, when he was imprisoned for short periods and when he was in a coma after the poisoning.
We know how to work and move forward even if he does not participate in the work on a daily basis.
But it is clear that we would prefer if he was back with us as our leader, says Volkov.
