Greek lawmakers are set Friday to approve Macedonia’s NATO accession.

Greek opposition parties reject the move, arguing that the name deal, which will end a 27-year dispute, concedes too much to Macedonia. But the left-led government in Athens controls enough seats in parliament to win the vote, which is expected Friday evening.

Greek approval of Macedonia’s NATO accession bid is the final step in the deal. Provided lawmakers vote for the motion, Greece’s foreign ministry will promptly notify the Macedonian government of the result.
