Russia has expelled a British diplomat it accuses of spying. The U.K. has described the claim as nonsense. Russia’s FSB says the diplomat was carrying out intelligence and subversive work. It says the diplomat sought sensitive information about the Russian economy in unofficial meetings. Authorities ordered the diplomat to leave within two weeks. The U.K. Foreign Office says Russia is running a coordinated campaign of harassment against British staff. It says it will not accept intimidation of embassy families. This is Russia’s second expulsion of a British diplomat this year. Both sides have traded expulsions since Russia sent troops into Ukraine in 2022.
