UK says Russia killed Navalny with dart frog toxin

The UK and allies say tests have shown the Russian opposition leader, Alexei Navalny, was killed by an extremely rare poision found in the skin of Ecuadorean dart frogs. The Russian government has denied any involvement. The US Secretary of State, Marco Rubio, has told the Munich Security Conference that Europe must show it shares Washington's values as part of a revitalised transatlantic relationship. Gisele Pelicot, who was drugged and raped by her husband and dozens of other men, has told the BBC she wants to visit him in prison to get answers.
