SKOPJE (Reuters) - A referendum to change the name of Macedonia failed to secure the 50 percent turnout required to make the vote valid, the head of the election commission said on Sunday.

“On this referendum it is clear that the decision has not been made,” election commission head Oliver Derkoski told reporters.
