Two years ago in Munich, Yulia Navalny sadly announced the passing of her spouse, Alexei Navalny, attributing it to the Russian state. Today, we have unveiled the harsh circumstances surrounding Navalny’s demise in a Russian prison. Tests have revealed the presence of a lethal toxin, epibatidine, typically found in Ecuador dart frogs, in Navalny’s body, suggesting it contributed to his death.
The Russian government possessed the capability, motive, and opportunity to employ this deadly substance against Navalny while he was detained. Alongside other nations investigating the matter, we hold Russia accountable for his untimely death.
This incident is just one aspect of a broader trend of malevolent activities that pose an increasing threat to European security and extend to British territories. From launching missiles at innocent civilians in Ukraine to spreading hybrid threats across Europe and beyond, Russia’s aggression is evident.
Following the Cold War, hopes for friendly cooperation between the UK and Russia have dwindled. Instead, we must prepare to counter Russian aggression, including cyber-attacks, disinformation campaigns, and attempts to undermine democracy across the continent.
The UK is taking a firm stance against Russia’s covert actions. Legal actions under the National Security Act have deterred Russian-linked individuals, and sanctions have been imposed on the GRU, Russia’s foreign military intelligence agency. Efforts to restrict Russia’s financial support for the Ukraine conflict, such as tightening control on Russia’s shadow fleet vessels, are underway.
Unity among nations is our most potent weapon. Collaborations with allies, including through NATO, bolster our domestic strength. During the Munich Security Conference, we have been working with partners on a unified plan of action, as outlined by the Prime Minister. Despite Russia’s attempts to sow division, its actions only strengthen our determination.
