The Main Committee, which met in the eastern town of Beli Manastir, also established an election team.
Glavas is not a member of the HDSSB but is the founder and president of the Croatian Democratic Assembly association, from which the HDSSB was born.
HDSSB president and Osijek County Prefect Kresimir Bubalo told the press after the meeting the party's fundamental task was to improve living conditions for all residents of the region.
He said he expected a good election result and that the HDSSB was open for post-election coalitions with every party whose goal was a better life for all citizens.
Bubalo said the election campaign would be based on the party's platform and not attacks on political adversaries.
