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.
The result of an election is so much more predictable if the candidate name on the form has a strict validation to “Putin”.
One of the elections where blank votes matter the most
Putin won over 100% of the vote in several regions. I’m sure filling out blank votes is child’s play by comparison.
