Greek Prime Minister Kyriakos Mitsotakis called on Turkish President Recep Tayyip Erdogan to explain whether a map presented by Erdogan's nationalist ally showing several large populated Greek islands as Turkish is official Turkish policy, AP reported.

“Take a good look at this map. Crete, Rhodes, Lesvos, Chios, Samos all consumed by Turkey,” Prime Minister Kyriakos Mitsotakis tweeted on Monday, along with a photo of Devlet Bahceli, the leader of a nationalist party allied with Erdogan, holding up a map showing Crete, Greece’s largest island, and all eastern Aegean Greek islands as being Turkish.

“Α fever dream of extremists or Turkey’s official policy? Another provocation or the true goal? President Erdogan must make his position clear on his junior coalition partner’s latest antics,” Mitsotakis tweeted.

The map was a gift to Bahceli from the ultranationalist Grey Wolves group, the youth organization affiliated with Bahceli’s National Movement Part, or MHP.

Grey Wolves head Ahmet Yigit Yildirim tweeted the photo with Bahceli and the map on Sunday, saying it was “to show the national consciousness’ border of our islands where the glorious Turkish flag fluttered for hundreds of years but that were usurped by Greece.”
