Former Serbian President Boris Tadic, who was voted out of the presidency earlier this month, looks to be in position to become the next Serbian prime minister.
Talks on a new governing coalition were due to start on May 28, when Tadic was expected to meet in Belgrade with incoming President Tomislav Nikolic.
Nikolic topped Tadic in the May 20 runoff election.
Reports say Nikolic may be forced to name Tadic prime minister because Tadic's Democratic Party will have more allies in the new parliament, enabling it to form the next cabinet, than Nikolic’s nationalist Progressive Party.
The Democrats and Progressives finished first and second in the recent polls but did not win enough to form a government on their own.
Tadic has said he would not include Nikolic's party in his new government.
