On Monday, Erdogan had warned he would veto the NATO plan unless the alliance agreed to designate a Kurdish militia as a terrorist group.
A veto by Turkey would have meant the defence plan would not have been accepted, public broadcaster Polish Radio’s IAR news agency reported.
Polish President Andrzej Duda, who spoke to Erdogan on Monday by phone, told reporters the next day in London that he hoped a “positive solution” could be found.
Erdogan agreed on Monday to meet with Duda and leaders of Baltic states at the high-profile NATO summit taking place in London from Tuesday to Wednesday. The gathering marks the alliance’s 70th anniversary.
