The 44-year-old lawyer and anti-corruption activist was admitted to a hospital in the Siberian city of Omsk on August 20 after he lost consciousness during a flight.
Those close to him claimed that he had been subjected to poisoning, while the Russian doctors who treated him claimed that they found “no trace” of it in his blood or urine.
Transfer him to Berlin
After he was in a coma, he was transferred two days later to the Charité Hospital in the German capital, at the request of his family.
The Russian medical team who initially treated him refused this step.
German doctors said tests indicated he had been poisoned.
On August 27, the Russian judiciary announced a preliminary investigation but said there was no evidence of poisoning.
Berlin said medical tests conducted by a German army laboratory had yielded “conclusive evidence” indicating that Navalny was a victim of poisoning with Novichok, a Soviet-era chemical weapon.
German Chancellor Angela Merkel requested clarification from Moscow on September 2.
NATO and the European Union called for an investigation.
On September 3, the Kremlin rejected allegations that Moscow was behind the poisoning.
The next day, a Russian toxicologist said that Navalny’s health had deteriorated due to a strict diet or exposure to stress or fatigue, stressing that no toxins were found.
Subsequently, NATO Secretary-General Jens Stoltenberg demanded that Moscow disclose the alleged Novichok program to the Global Chemical Weapons Watch.
Germany, which holds the rotating presidency of the European Union, said it will discuss possible sanctions against Russia on September 6.
Waking up from coma
The next day, Navalny was released from the coma and began to respond.
Labs confirm poisoning
On September 14, laboratories in France and Sweden confirmed Germany’s findings that Navalny had been poisoned with Novichok.
French President Emmanuel Macron urged Vladimir Putin to shed light on an “attempted murder”, while Putin condemned the “baseless” accusations.
Leave the hospital
Navalny posted a message on Instagram on September 15 stating that he could breathe without medical assistance, and attached it to a picture of him appearing emaciated with his wife Julia and his two children sitting on a bed.
Two days later, Navalny’s aides said they discovered traces of Novichok on a bottle taken from the hotel in Siberia where he stayed before he fell ill.
On September 21, Navalny said that Western laboratories had found traces of Novichuk on his body and on his body and demanded that Moscow return the clothes he was wearing on the day of the accident.
The next day, the dissident was discharged from the Berlin hospital, who said that his “full recovery is possible”.
After this, the Kremlin declared Navalny welcome to return to Moscow.
Navalny’s spokeswoman said Russia froze his assets while he was in a coma.
On October 1, Navalny accused Putin of being behind his poisoning and said he would not give the Russian president the pleasure of being in exile.
Dmitry Peskov, Putin’s spokesman, accused Navalny of working for the CIA, and described his claims as “unacceptable and baseless.”
Recognition and registration
But in December, Navalny revealed a recorded phone call between him and a Russian FSB agent in which the latter admitted that he had tried to kill the opponent by putting poison in his underwear, after Navalny had caught him by pretending to be a senior security commander who wanted answers to why the poisoning failed.
The Russian Federal Security Service described the phone call as a “provocation aimed at discrediting” the agency.
In mid-January, Navalny posted a video on Instagram announcing his intention to return home despite his threat of imprisonment by the Russian authorities.
“It wasn’t my choice to come to Germany,” he joked. “What bad thing could happen to me in Russia?”
He was arrested shortly after landing at Sheremetyevo airport after his last-minute flight was redirected from another airport in Moscow to avoid possible protests from his supporters.
