On 20 March 2016, a deal between the EU and Turkey to tackle the migrant crisis formally came into effect. The agreement was intended to limit the influx of irregular migrants entering the EU through Turkey. A central aspect of the deal is the return to the Turkish capital of Ankara any irregular migrant who is found to have entered the EU through Turkey without having already undergone a formal asylum application process. Those that had bypassed the asylum process in Turkey would be returned and placed at the end of the application line.
