In 2006, Alexander Litvinenko, a former Russian spy turned Kremlin critic, was poisoned with Polonium-210, a rare and lethal radioactive substance, in a London hotel. The subsequent investigation implicated Andrei Lugovoi and Dmitry Kovtun, two former Russian agents, as the perpetrators, and pointed to the involvement of the Russian state. The case sparked international outrage and heightened tensions between the United Kingdom and Russia, leading to diplomatic expulsions and sanctions. Litvinenko's death became a symbol of the dangers faced by those who opposed the Russian government and shed light on the murky world of espionage and political intrigue.
