As for the referendum on early elections, Leko said on Croatian Radio that collecting signatures was legitimate but that early elections, like regular ones, were always a referendum.
"It's legitimate to seek early elections because every democratic government is subject to examination and control, including early elections," he said.
Speaking of a December 1 referendum to decide whether the Constitution should define marriage as a heterosexual union, he said, "We must build a society of tolerance and understanding, and not a society of exclusion."
