A student protest movement has gripped Serbia for two years. This weekend it will try to take power

Unorthodox campaign is challenging the ruling party's 12-year reign with a bold democratic experiment

On a cool autumn evening, a team of Serbian student volunteers went canvassing in the housing estates of Krnjaa, a Belgrade suburb. They were equipped with lanyards emblazoned with the word victory", a stock list of questions and a mobile app that mapped visited homes and the level of support in each.

The volunteers were part of a mass student movement, Student List, that has rocked Serbia with two years of constant protests. On Sunday, the group will represent the most serious challenge Aleksandar Vui has faced in his 12 increasingly authoritarian years in power, by putting forward their own candidates in parliamentary elections.
