Immense crowds are queueing not only at polling stations in Serbia but also outside the Embassy of the Republic of Serbia in Ljubljana, where people waiting have been singing to pass the time. The ballot puts to Serbian voters a blunt choice: a continuation of the rule of Aleksandar Vučić's Serbian Progressive Party, or the political change being promised by a rival force. That alternative is the Student List, a grouping that grew out of the mass protest movement. The thick crowd outside the Ljubljana embassy shows the vote has reached Serbian citizens living abroad as well.
