Alexei Navalny, Putin's challenger
阿列克謝·納瓦爾尼：普丁的挑戰者

The anti-corruption campaigner has built up a surprisingly large popular movement ahead of presidential elections next March, says Kathrin Hille. But he is short on policies and numbers and can appear out of his depth. Does he offer a genuine alternative, asks Kathrin.
這位反腐敗活動家在明年三月的俄羅斯大選前掀起了一場民衆運動，獲得了數量驚人的擁躉。但他在政策上仍有不足，支持者與普丁相比也處於劣勢，他會怎樣面對這種困難的情況？他能夠成爲俄羅斯人在普丁之外的另一個選擇嗎？
