Lagumdzija was speaking at a convention of his party, announcing a fierce campaign for municipal elections due in early October.
"Dodik says BiH is incapable of existing and that the only question is how to separate peacefully, that the Council of Ministers has a hard time functioning and that Lagumdzija must go. Dodik says it and Tihic supports it," he said in Zenica, adding that the SDP would prevent the division of Bosnia.
The SNSD has launched the dismissal of Lagumdzija as foreign minister after he unilaterally instructed the Bosnian ambassador to the UN on how to vote on a resolution on Syria without consultations with the Serb member of the state Presidency.
Lagumdzija said the SDP had made a mistake when it entered a coalition with the SDA, and regretted that state Presidency member Zeljko Komsic had left the SDP.
