Prime Minister Kyriakos Mitsotakis joined 21 other European Union leaders in signing a letter to the bloc’s leadership asking for a coordination of migration policies and criticizing Spanish Prime Minister Pedro Sanchez’s project of regularization of undocumented migrants.

The Spanish prime minister accuses EU partners of taking “selfish” and “unlawful” stances in response to the surge of migrants from Morocco.

A majority of EU countries called on Saturday for emergency talks on the sudden inflow of tens of thousands of migrants into Spain's enclave of Ceuta in North Africa.
