Yulia Navalnaya, the widow of the Russian opposition leader Alexei Navalny, said that two foreign laboratories had confirmed her husband was poisoned, after tests on biological samples secretly smuggled out of Russia.
Navalny, 47, died suddenly on 16 February 2024, while being held in a jail about 40 miles (64km) north of the Arctic Circle, where he had been sentenced to decades in prison to be served in a “special regime”.
