The opposition in Croatia looks likely to win a parliamentary election.
The ruling conservative HDZ party is beset by corruption scandals and a poor economy.
Opinion polls suggest the Kukuriku coalition will win enough votes to form a majority in the 151 seats of parliament.
It has promised austerity measures and steps to revive industry and attract foreign investment.
The HDZ party has dominated Croatian politics since its 1991 independence. It is well behind in the polls.
Croatia is due to sign a European Union accession treaty next week that will allow it to formally join in 2013.
