The student movement Student List, which has kept up constant protests in Serbia for two years, is fielding 250 candidates in Sunday’s parliamentary election and, according to the Guardian, poses the most serious challenge Aleksandar Vučić has faced in 12 years in power that the paper describes as increasingly authoritarian.

Vučić stepped down as president last month, five months before the end of his second and last term under the constitution, with the aim of extending his hold on power as prime minister at the head of his Serbian Progressive party (SNS).
