(ANSA-AP) - ATHENS - Political leaders in both Greece and Macedonia are meeting to discuss ways to resolve a longstanding dispute over the name of Greece's northern neighbor. Greece has disputed Macedonia's right to call itself by a name shared with its own northern province of Macedonia ever since the Republic of Macedonia became independent in 1991. It has blocked Macedonia's accession to NATO. Greek Prime Minister Alexis Tsipras met Saturday with the leaders of all opposition parliamentary parties except for far-right Golden Dawn. Although none gave him carte blanche for negotiations, he focused his criticism on opposition leader Kyriakos Mitsotakis, showing that the name dispute has become a domestic issue as well. In Macedonia, a meeting under President Gjorge Ivanov went late into the night and no statements have been issued.(ANSA).
