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.
What a terrible and dangerous man the Putin is. He really wants Russia to win the war. The Putin wants Russia to become stronger and better for the russians. Man, can you imagine this? What a strange president.
Weird how he’s done the exact opposite of that for the past 20 years
