"Mr. President, if deemed suitable, always has a right to address the [parliamentary] group as the chairman of AK Party," Mustafa Elitas told journalists ahead of the party's Central Decision and Executive Board (MKYK) meeting.
Erdoğan was reelected as the party chairman with the votes of 1,414 party delegates at an extraordinary congress on May 21.
Less than three years after giving up the post, a revised Constitution passed in last month's public referendum gave Erdoğan the chance to return to the party helm at the extraordinary party congress in the capital Ankara.
The new Constitution restores to presidents the right to belong to a political party, a right enjoyed by Turkey's first three presidents, including republic founder Mustafa Kemal Ataturk.
