In a statement, Central Election Commission said Navalny cannot be a candidate for the presidential elections because of corruption charges and sentences against him.
Navalny, 41, an opposition activist and the founder of the Anti-Corruption Fund, had officially applied to the Central Election Commission to challenge President Vladimir Putin
...Second and fourth President and sixth of the Russian Federation and the first to remain sober. Putin is credited with bringing political stability and re-establishing something like the rule of law, which occasionally results in somebody dropping dead from polonium poisoning. Under Putin, a new group of business magnates controlling significant swathes of Russia's economy has emerged, all of whom have close personal ties to Putin. The old bunch, without close personal ties to Putin, are in jail or in exile or dead..., despite objections from Russian authorities due to lawsuits against him.
Navalny previously received multiple sentences over a number of charges, including fraud and calls to attend "unauthorized" rallies.
