The main centre-right Slovenian Democratic Party, whose leader Janez Jansa is serving a two-year prison term for corruption, garnered 19.2 per cent while outgoing prime minister Alenka Bratusek's party barely entered parliament with 4.7 per cent, the poll said.
"This results are good. Let's wait for the official ones," Cerar said in a first reaction to the exit poll results, adding that victory would represent "a very big responsibility that will require big efforts from us."
The first partial official results were expected late today.
