Communists carry portraits of former Soviet leader Josef Stalin as they march along Kremlin Towers during May Day demonstration in Moscow, Friday, May 1, 2015. As in Soviet times, tens of thousands of cheerful workers paraded across Red Square despite a chilly rain, but instead of red flags with the Communist hammer and sickle, they waved the blue flags of the dominant Kremlin party and the Russian tricolor. Participants, who came in groups organized by their trade unions, said the May 1 parade was a tradition going back to their childhood. (AP Photo/Denis Tyrin)
