Why Serbian elections are so important - as students challenge 12 years of Vučić rule

Rallies have been taking place across Serbia on Thursday, the final day of campaigning ahead of a snap election billed as a referendum on the country's future. After two years of student protests, Serbians vote for a new parliament on Sunday in elections that threaten populist leader Aleksandar Vučić's 12 years in power. The main threat to Vučić's dominance in Serbian politics comes from a two-year-old student movement, but there are concerns surrounding the fairness of the vote.
