What did the opposition parties want and AKP rejected?
Turkish Forum
Turkey’s ruling Justice and Development Party (AKP) has rejected a proposal for a constitutional amendment to protect the civil rights of homosexuals.
AKP lawmakers defeated the proposal, advanced by opposition parties, to include “sexual orientation” among the categories qualifying for constitutional protection. An AKP representative explained that the party, headed by President Recept Tayyip Erdogan, does not think it appropriate to include a reference to homosexuals in the nation’s constitution.
