Jailed Kremlin critic Alexei Navalny has been awarded the European Parliament's annual human rights prize for his efforts to challenge President Vladimir Putin's grip on power.
Navalny, 45, who was poisoned in August 2020 by what Western nations said was a nerve agent, is serving a two-and-a-half-year sentence for parole violations he says are trumped up.
The EU has imposed sanctions on Russian officials over Navalny's poisoning and imprisonment.
"He has fought tirelessly against the corruption of Vladimir Putin's regime. This cost him his liberty and nearly his life. Today's prize recognises his immense bravery and we reiterate our call for his immediate release," the European Parliament said on Twitter on Wednesday, announcing Navalny as the winner.
Moscow denies any wrongdoing and accuses the EU of interfering in its domestic affairs. It has also denied Western accusations that Navalny was jailed for his political activities and said he was punished for breaking the law.
Past winners of the 50,000 euro Sakharov Prize for Freedom of Thought, named after Soviet dissident Andrei Sakharov, include South African president Nelson Mandela, Venezuela's democratic opposition and Pakistani education activist Malala Yousafzai.
NATO Secretary-General Jens Stoltenberg welcomed the parliament's decision.
"I think it's an important recognition of the important role he has played for many years in supporting democratic values and being a strong voice in Russia," Stoltenberg told a news conference in Brussels, calling for his release.
Navalny's team wrote on the messaging app Telegram: "Putin calls Navalny a criminal blogger, but he is alone in this. Alexei Navalny is a politician who fights for justice despite all the threats and assassination attempts."
"And we are certain that Putin is not pleased to hear about this," the team said.
Navalny said on October 11 that a prison commission had designated him an extremist and a terrorist, which he denies.
Navalny's movement suffered an earlier blow in June when a court ruled its activities to be extremist.
Many of his allies have had their homes raided or their freedom of movement restricted, and some have fled abroad.
Last month Russia opened a new criminal case against Navalny that could keep him in jail for a further decade.
