"Uncertain to the end," Croatian-language daily Poslovni dvevnikwrites on its Monday front page, a day after Croatia's conservative opposition claimed a narrow victory in the country's first election since it joined the European Union in 2013.

The Croatian Democratic Union (HDZ) has declared victory after Sunday's parliamentary elections, but the leading opposition party failed to win an outright majority and now faces a tough task to form a coalition government, newspaper Ve�ernji List reports.

After a campaign that largely focused on the migrants crisis, HDZ won 59 seats, with the ruling Social Democrats at 56 seats. A third group, made of right-leaning independent candidates, called Most (Bridge in Croatian) however won a surprising 19 seats and announced it would refuse to enter a coalition government with the two main political forces, apparently leaving them short of the necessary support to form a government.
