"There will no longer be a presidential guard, there is no purpose, there is no need," Yildirim said, speaking to A Haber channel.
The presidential guard is a regiment numbering up to 2,500 people but at least 283 of its members had been detained after the coup.
Turkey also detained a senior aide to the US-based cleric Fethullah Gulen whom it blames for the coup attempt aimed at ousting President Recep Tayyip Erdogan, an official said yesterday.
Gulen denies being behind the failed coup.
The official said Hanci "apparently" entered the country two days before the attempted putsch that erupted late on July 15.
