Despite recent turbulence in Turkey, the migration deal must be adhered to, said Manfred Weber, a member of the European Parliament Thursday.
"The refugee pact is working. Smuggling in the Aegean Sea, for instance, has an end. There is no reason to question the agreement," the German politician told dpa.
Adopted in March, the plan allows the European Union to send Syrian asylum seekers from Greek islands back to Turkey, as part of a bid to undercut migrant smuggling networks.
For every Syrian that Turkey takes back from Greece, they are allowed to send another Syrian to the EU legally.
"After this acute phase, we must reorder the relationship with Turkey," Weber said.
Turkey decalred a nationwide state of emergency after launching a drastic purge of state institutions following a failed coup by the military.
