Boris Nadezhdin received more than 100,000 signatures from Russians for his presidential candidacy. Now the Russian election commission has declared that it has found “errors,” as the Guardian reports.

While Nadezdin has not yet been disqualified, news from the Central Election Commission suggests he could be disqualified ahead of the election. He was formerly an advisor to Sergei Kiriyenko, Putin's domestic policy chief, and his close contacts with the government are controversial. He is scheduled to appear before the commission on Monday to examine the “ errors” in his signatures.
