Bulgaria’s Premier Boyko Borissov sent a letter to the President of the European Council Donald Tusk, where he insists that the European Union should provide for the protection of all external borders with Turkey. Premier Borissov wrote that the EU should not only focus on the protection of the Greece-Turkey sea border, because the direction of the migrant’s flow is unpredictable. Premier Borissov also insisted that the EU-Turkey negotiations should cover the land border between Bulgaria and Turkey, Greece and Turkey and the EU-Turkey border in the Black Sea. Sofia expressed the stand that the issue regarding the lifting of the visa regime for Turkish citizens should not be bound up with dates. It should rather depend on the results of the readmission agreement between the EU and Turkey. Bulgaria also insists that the EU should provide the necessary resource to all countries affected by increased migratory flows, so that those countries can fulfill the agreement to send back all illegal migrants to Turkey.
