Socialist Red-Green Alliance parliamentarian Soren Sondergaard told Danish public television TV2 that Ankara accused him of "promoting a terrorist organization".

The Danish deputy was reportedly blocked by Ankara on the grounds that he had visited the Syrian Democratic Forces (SDF) in the past.

“It is entirely true that I visited the Syrian Democratic Forces fighting the Islamic State,” Sondergaard said, adding that he was “proud” of this.

Stating that the OECD made a formal complaint to Ankara, the Danish deputy said: “A country cannot elect parliamentarians who act as observers. This casts a shadow on the Turkish elections, it shows that they want to keep the elections under control."

The Danish deputy also acts as an observer of the Organization for Economic Cooperation and Development (OECD) and sometimes the Organization for Economic Cooperation and Development.
