She repeatedly blamed Vladimir Putin directly for Navalny’s death.

She said: “Three days ago, Vladimir Putin killed my husband … We know exactly why Putin killed Alexei three days ago. We will tell you soon about it. We will also definitely find out who exactly and how exactly this crime was committed. We will name names and show faces.”

Novichok, the nerve agent Navalnaya believes was used to kill Navalny, was famously used in 2018 in the Salisbury poisonings of Sergei and Yulia Skripal.

It ended up being a botched assassination attempt on Sergei, who was a former Russian military officer who was working with British intelligence agencies in Salisbury. Both spent days in the hospital before being discharged, surviving the event.

British authorities say the poisoning had almost certainly been approved “at a senior level of the Russian state.” Moscow has vehemently denied the allegations.

While the Skripals survived, the attack later claimed the life of a British woman and left a man and a police officer seriously ill.

Navalnaya continued: “The most important thing we can do for Alexei and for ourselves is to continue to fight. I will continue the life work of Alexei Navalny. I call on you to stand with me.”

Following the news of her husband’s death, Navalnaya spoke at a conference in Germany, denouncing the lies of the Putin regime. She said: “They are lying constantly. They will be brought ot justice, and this day will come soon.”

Russian prison authorities announced on Friday that Navalny fell unconscious and passed away after feeling unwell on a walk. The Kremlin has denied involvement in his death.
