G17 Plus

Bošnjak joined the G17 Plus network on its formation in 1999 and became a more prominent figure in the organization after it became a political party in 2002.^[2]

She received the sixteenth position on the G17 Plus electoral list in the 2003 Serbian parliamentary election and was awarded a mandate the list won thirty-four seats.^[3] (From 2000 to 2011, mandates in Serbian parliamentary elections were awarded to sponsoring parties or coalitions rather than individual candidates, and it was common practice for the mandates to be assigned out of numerical order. Bošnjak did not automatically receive a mandate by virtue of her list position, though she was included in her party's delegation all the same when the assembly met in January 2004.)^[4][5] G17 Plus subsequently participated in Serbia's coalition government, and Bošnjak supported the administration in parliament. She served on the committee on relations with Serbs outside Serbia, the committee on transport and communications, and the committee on trade and tourism.^[6]

Bošnjak was the G17 Plus candidate for mayor of Belgrade in the 2004 Serbian local elections and finished in seventh place. She also appeared in the fourth position on the party's electoral list for the City Assembly of Belgrade in the same election and was given a mandate when the list won five seats.^[7][8] She later served on the Belgrade city council (i.e., the executive branch of the city government) with responsibility for urban affairs.^[9]

She resigned from the national assembly in May 2006, shortly after Miroljub Labus stood down as G17 Plus leader.^[10] She was not a candidate for the Belgrade assembly in the 2008 Serbian local elections.

Social Democratic Party of Serbia

Bošnjak subsequently joined Rasim Ljajić's SDPS. This party contested the 2014 Serbian parliamentary election on the electoral list of the Serbian Progressive Party; Bošnjak received the ninetieth position and was re-elected to the assembly when the list won a landslide victory with 158 out of 250 mandates.^[11] (Following a 2011 reform, all mandates were awarded to candidates on successful lists in numerical order.) In her second term, Bošnjak was a member of the committee on the rights of the child and the committee for spatial planning, transport, infrastructure, and telecommunications. She was also the leader of Serbia's parliamentary friendship group with the Holy See and a member of the friendship groups with Argentina, Australia, Belgium, Bosnia and Herzegovina, Brazil, Canada, Croatia, Cuba, Cyprus, France, Germany, Greece, India, Indonesia, Iraq, Israel, Italy, the Republic of Macedonia, Montenegro, Portugal, Slovenia, Spain, Switzerland, the United States of America, and Venezuela, as well as the friendship group with Sub-Saharan Africa and the group with Chile, Colombia, Paraguay, and Uruguay.^[12] She was not a candidate for re-election in 2016.
