Russia's Supreme Court has ordered the release of opposition activist Ildar Dadin, who is the first person to be convicted under new laws on protests. <br/><br/>The court said the criminal case against him should be dismissed and he had a right to rehabilitation. Mr Dadin, jailed in December 2015, has been serving two-and-a-half years for a series of protests. Last November he said he is tortured in prison in north-west Russia. The authorities denied the claims, but transferred him to another prison. <br/><br/>Today's court ruling came after Russia's constitutional court earlier this month concluded that Mr Dadin's case needed to be reviewed.
