Vučić had spent two terms as president and could not seek a third term, so was leading his Serbian Progressive Party (SNS) with the aim of returning to the post of prime minister, which he left in 2017.
The Student List’s lead candidate Ilija Srdanović told BBC Serbian: “This will be a free state.”
He said the anti-corruption movement, which had attracted anti-government voters across Serbia, hoped to “free the country from tyranny”.
Vučić made his announcement at the headquarters of his Serbian Progressive Party (SNS) in the capital Belgrade.
There were celebrations on the streets of the city, with people dancing and chanting “victory”, cars honking, and fireworks set off. “Serbia is free,” one student told the BBC. “It’s a miracle.”
The centre of Novi Sad – the northern city that triggered the student-led protests – was crowded. “Everything is going to get better now,” David Vasić, one of those celebrating, told the BBC Serbian.
The Student List – which has no obvious leaders and whose members are not used to politics – had attracted anti-government voters across Serbia.
It decided to field candidates to the 250-member parliament from across Serbian society including doctors, actors, academics and sports personalities.
