ANKARA, June 14 (Reuters) – Sweden should not expect a change of attitude from Ankara on its NATO membership bid at the Western alliance’s summit next month unless it prevents anti-Turkey protests in Stockholm, Turkish President Tayyip Erdogan was quoted as saying on Wednesday.

Turkey cannot approach Sweden’s NATO bid positively while “terrorists” were protesting in Stockholm, and Turkey‘s position would be made clear once again in talks with Swedish officials in Ankara on Wednesday, Erdogan was quoted as telling reporters on a flight returning from Azerbaijan on Tuesday.

Erdogan made his comments before officials from Turkey, Sweden, Finland and NATO met on Wednesday in Ankara for talks to try to overcome Turkish objections that have delayed Sweden’s NATO membership bid.

In March, Turkey ratified Finland’s bid for membership of the North Atlantic Treaty Organization, but still objects to Sweden joining the alliance, as does Hungary.

In justifying its objections to Swedish membership, Turkey has accused Stockholm of harbouring members of Kurdish militant groups it considers to be terrorists.

Sweden says it has upheld its part of a deal struck with Turkey in Madrid aimed at addressing Ankara’s security concerns, including bringing in a new anti-terrorism law this month. It says it follows national and international law on extraditions.

Turkish-Swedish tensions were most recently fuelled by an anti-Turkey and anti-NATO protest in Stockholm last month, when the flag of the Kurdistan Workers Party (PKK) militant group, outlawed in Turkey as well as in the European Union, was projected on to the parliament building.

Commenting on Sweden’s recent legal changes Erdogan said:

“This is not only a matter of a law amendment or a constitutional change. What is the job of the police there? They have legal and constitutional rights, they should exercise their rights. The police should prevent these (protests).”

On the day he was having talks with NATO Secretary-General Jens Stoltenberg earlier this month, a similar protest was held in Stockholm, Erdogan said. He added that he also told Stoltenberg Sweden should prevent such actions to secure Turkey‘s approval for its NATO membership.

After meeting Erdogan, Stoltenberg said a deal on Sweden joining the alliance could be reached before the NATO summit in Vilnius next month.
