A statement from Mesic's office said the three-week campaign period would begin Nov. 3 and end with the election of a new government to a four-year term. Some 4 million Croatians are eligible to vote in the election.
The ruling center-right Croatian Democratic Union, or HDZ, and the leading opposition leftist Social-Democratic Party, SDP, are expected to wage a close contest for control of the one-chamber parliament of 160 deputies.
Public polls have indicated neither HDZ nor SDP would win a clear victory to form a Cabinet without a coalition with minor parties.
