The coup, the purges that have followed and the recent constitutional referendum have all strained the relationship between Erdogan's Turkey and the European Union. In many ways Erdogan is beginning to realign Turkey away from the long term Turish plan to join the EU. However, the immigration deal remains of broad benefit to Turkey. Additionally, most European leaders would see a moral case for looking after Syrian refugees and also observe that Turkey is unlikely to be able to absorb the 2.7 million refugees they have received without help. As such both sides would most likely still see a lot of value in the immigration deal. The one major strain may be changing attitudes from EU voters and a possible corresponding change in the attitudes of EU leaders.
