Berlin (AFP) -
Kremlin critic Alexei Navalny accused President Vladimir Putin of being behind his poisoning, as he vowed to return to Russia to press on with his opposition campaign.
In the first media interview since his poisoning, Navalny gave harrowing details of his collapse on a flight from Tomsk to Moscow after he was poisoned by what the West identified as the Soviet-era nerve agent Novichok.
The 44-year-old anti-corruption campaigner also said he would not be cowed by the experience, pledging to get fit as soon as possible to continue his fight.
'Not returning would mean that Putin has achieved his aim. And my job now is to stay the guy who's not afraid,' he told Spiegel weekly.
'I will not give Putin the gift of not returning to Russia,' he said, adding that for him, 'Putin is behind this act, I don't see any other explanation.'
Navalny was evacuated to Berlin for treatment after he collapsed in August following a campaign trip to support opposition candidates in local elections.
The Kremlin critic was discharged just over a week ago and his first comments to the press came as European leaders were holding a summit during which the question of a response to Russia may be raised over his case.
Germany, which holds the presidency of the EU, has said toxicology tests show he was poisoned by the Soviet-era nerve agent Novichok.
France and Sweden have independently corroborated Germany's findings.
Chancellor Angela Merkel's government has also warned Moscow of possible sanctions if it failed to thoroughly investigate the case.
The Kremlin has firmly denied allegations of involvement and accused Western leaders of launching a disinformation campaign over the opposition leader's illness.
Instead, it pointed to tests carried out by Russian doctors who first treated Navalny showing no toxic substances.
On Thursday, the head of Russia's lower house of parliament, Vyacheslav Volodin retorted that Putin had 'saved' Navalny's life.
He also accused the opposition leader had instead been 'working with the security services and authorities of Western countries.'
- Juggling -
Navalny had arrived in Berlin in a coma and on mechanical ventilation. He was finally discharged on September 22 after spending 32 days in the Charite hospital in the German capital, including 24 days in intensive care.
In a sign of how seriously Merkel was taking the case, the German leader paid a visit to Navalny in the hospital.
Merkel has also stressed repeatedly that 'only Russia can and must answer' questions on the case.
For Navalny, the 'most important fact is Novichok' as he pointed the finger at Putin for ordering the poisoning.
Only the leaders of Russia's secret services can make the call to deploy the poison, he said.
Despite his harrowing experience, he said he will press on with his activities when he returns to Russia.
'I will keep travelling through Russia's regions, stay in hotels and drink water that's in the rooms. What I can do otherwise? One cannot do much to counter Putin's invisible murderers.'
For now he is staying in Berlin with his wife and son as he undergoes the long process of rehabilitation.
'I take walks in the park in the morning, that's my task, then I do some exercises with my doctor, then in the evenings I walk again,' he said.
He has also begun juggling exercises, he said, 'to improve coordination, so that the hands will move in the same direction as the eyes'.
- Tensions -
Navalny's poisoning has heightened tensions between Russia and the West, in particular aggravating the relationship with Germany.
Merkel had always insisted on keeping channels of dialogue open with Moscow but she has sharpened her tone lately, with Navalny's case coming a year after a murder in a central Berlin park that German prosecutors say was ordered by Russia.
Navalny aides said that German experts found Novichok on a water bottle taken from the hotel room where he stayed before being taken ill.
The bottle appears to have been key evidence for Germany's conclusion that the lawyer and outspoken critic of President Vladimir Putin was poisoned with the deadly nerve agent.
Novichok was also used to poison ex-double agent Sergei Skripal in Salisbury, England, in 2018. He survived.
