Overview

• Yulia Navalnaya says supporters smuggled biological samples abroad after his February 2024 death and two laboratories in different countries independently concluded he was poisoned.
• She has not identified the laboratories or the substance involved and is urging full publication of the analyses, alleging political hesitation by Western governments.
• Russian investigators have cited a "combination of diseases" including arrhythmia as the cause of death; the Kremlin denies involvement, and spokesman Dmitry Peskov said he was unaware of the new claim.
• Navalny previously survived a 2020 Novichok poisoning confirmed by German, French and Swedish laboratories and the Organization for the Prohibition of Chemical Weapons.
• Navalny's allies released images and staff testimony from the Arctic prison describing convulsions, vomiting and delayed resuscitation, while saying no surveillance footage from his final hours has been made public.
