Navalny: a savvy and determined Kremlin foe

The 15-day jail sentence imposed Monday on Alexei Navalny is nothing new for the Kremlin's most visible domestic foe, and is unlikely to be more than a brief interruption of his campaign against what he calls "the party of crooks and thieves." He's repeatedly been jailed, endured a year of house arrest and three convictions that could have brought him significant prison time.

Amid all the detentions, the 40-year-old Navalny has relentlessly pursued corruption investigations that allege the top tier of Russian officials, including Prime Minister Dmitry Medvedev, have amassed extraordinary wealth, living lives of unparalleled luxury behind their modest public images.
