AK Party Group Deputy Chairman Mustafa Elitaş told the NTV that the party will offer membership to the president after April 27-28, which are the dates Turkey's Supreme Election Board (YSK) is expected to announce official results of the referendum on the Official Gazette.
"We will be honored if he accepts the invititation" Elitaş said.
Erdoğan had to cut his ties with the AK Party after being elected as president in 2014, in line with the constitution, but the constitutional reforms will allow the president to keep party affiliation.
Over 58 million voters participated in Sunday's referendum, in which the "Yes" campaign gained 51.4 percent of the vote, while the no campaign gained 48.6 percent of the vote.
