Greek Prime Minister Alexis Tsipras said on Tuesday that FYROM has agreed to be called Severna Makedonija ("Republic of North Macedonia") as part of an agreement to settle the name dispute between the two nations.
The agreement will be signed by the foreign ministers of both countries and will then head to FYROM's parliament for approval, said the Greek premier in a televised speech.
"I am deeply convinced that this agreement will be a diplomatic victory and also a large historic oppurtunity," he said  
If FYROM does not make the necessary changes to its constitution, as foreseen in the deal, then this will cancel the invitation to join the NATO military alliance and start induction talks with the European Union, added Tsipras.
