MOSCOW—Russian authorities announced a new criminal charge against Kremlin critic Alexei Navalny on Wednesday, the latest move in a clampdown ahead of September’s parliamentary election that could add as much as three years to his prison term.
Navalny, President Vladimir Putin’s fiercest domestic critic, is serving a 2.5-year sentence for parole violations he calls trumped up. He was arrested after flying back from Germany where he had recovered from a nerve agent poisoning.
