Mogherini said that Turkey will not become EU member if it allows death penalty. However, Turkey's President Recep Tayyip Erdoğan stated that returning the death penalty will not affect State's relations with EU. He said this in an interview with Al Jazeera.
"If the EU respects democracy it will accept people's will," he said, stressing that the people have voiced this demand.
"They took to the streets and kept saying 'capital punishment, capital punishment, capital punishment", Erdogan adds.
According to him, if parliament makes that decision, then the duty of the authorities in power is to pave the way for this punishment to be reintroduced. He added that the US, Russia, China and in many other countries have capital punishment.
The Turkish president said he believed foreign countries might have been involved in the failed coup attempt, though he declined to name any.
Turkey abolished the death penalty in 2004 under reforms aimed at obtaining European Union membership.
