Independent politician Yekaterina Duntsova wanted to run on a platform to end the war with Ukraine.
But the electoral commission voted unanimously to reject her candidacy three days after her application, citing 100 “mistakes” on her form.
Ms Duntsova said she would appeal the decision at the Supreme Court.
The commission said 29 people have so far filed to run for the presidency. But after today’s decision, Mr Putin remains the only candidate to be able to register as a candidate.
Not that I want that to drop out of the media circuit but there’s only so much to report on. How many different ways can you say a politician disappeared? Especially when the guy responsible is a dictator that simply won’t answer any questions regarding the person at hand.
