Radovanović appeared in the eighty-fourth position on the Progressive Party's Let's Get Serbia Moving electoral list in the 2012 Serbian parliamentary election.[2] The list won seventy-three seats, and she was not immediately elected. The Progressives subsequently formed a coalition government with the Socialist Party of Serbia (SPS) and other parties, and a number of delegates elected on the SNS list resigned to take government positions. Radovanović was given a replacement mandate on 29 August 2012 and took her seat in the assembly on 31 August.[3] During her assembly term, she was a member of the education committee,[a] a deputy member of the committee on culture and information and the spatial planning committee,[b] and a member of the parliamentary friendship groups with Austria, Cyprus, Greece, Italy, Japan, Portugal, Russia, Slovenia, Ukraine, and the United States of America.[4]
In 2013, the Progressive Party's city board for Šabac was temporarily dissolved amid serious internal divisions, and Radovanović was appointed to a three-member board of trustees.[5]
She was given the 207th position on the SNS's list for the 2014 parliamentary election and was not re-elected even as the list won a landslide victory with 158 out of 250 seats.[6] She subsequently left the SNS and was briefly a member of a local Šabac party called the Village–City Initiative. She launched her own political group called the Progressive Movement (Napredni pokret) in November 2015, indicating that it would be particularly focused on issues of gender equality.[7]
The Progressive Movement contested the 2016 Serbian local elections in Šabac and fell below the electoral threshold for assembly representation.[8] Radovanović has not sought a return to political life since this time.
