Volkswacht Bodensee - Greek PM slams N. Macedonian president in new name row

The Balkan nation added "North" to its title in 2018 to end a long-running dispute with Greece, which for years blocked Skopje's bid to join NATO and the European Union.

Greece also has a province called Macedonia, which borders its northern neighbour, and the two countries have also been at loggerheads over the heritage of Alexander the Great, who created one of the largest ancient empires in history.

In her oath Sunday, President Gordana Siljanovska-Davkova said she would "respect the constitution and the laws and... protect the sovereignty, territorial integrity and independence of Macedonia".

It prompted Greece's ambassador to Skopje to walk out of the inauguration ceremony in protest, according to local media reports.

And on Monday Mitsotakis rounded on her. "The provocative choice of the new president of North Macedonia to violate the official text of her oath and call her country by a different name is an illegal and impermissible initiative," he wrote on X, formerly Twitter.

The official written text of Siljanovska-Davkova's address included the official name of "North Macedonia", an AFP reporter saw.

Her country added "North" to its name following an historic agreement with Mitsotakis's left-wing predecessor, Alexis Tsipras.

But Siljanovska-Davkova's party, the nationalist VMRO-DPMNE, opposes the accord and has refused to acknowledge the country's new name.

The right-wing party triumphed in parliamentary and presidential elections on Wednesday, with the ruling Social Democrats (SDSM) conceding defeat even before official results were announced.

Skopje's 2018 Prespa Agreement with Athens to add the prefix "North" to its name ended decades of quarrelling between the neighbours.

Greece for years opposed North Macedonia joining NATO -- it finally became a member of the alliance in 2020 -- and delayed talks on it eventually joining the European Union over the issue.

The conservative Mitsotakis, whose party had strongly opposed the 2018 agreement, said Siljanovska-Davkova's speech on Sunday violated both that accord and North Macedonia's constitution.

He warned on Monday that "any progress in bilateral relations, as well as any steps taken by Skopje towards Europe, depend on the sincere observance of what was agreed.

"We will not accept similar slip-ups," the Greek premier added.

European Commission president Ursula von der Leyen said on X on Sunday that North Macedonia must keep to "the path of reforms and full respect for its binding agreements, including the Prespa Agreement", to continue its path towards EU accession.

The return to power of the nationalist right in North Macedonia also risks reigniting tensions with Bulgaria, which has long blocked EU accession for Skopje due to linguistic and historical disputes.
