Ahmad Tibi is the most senior Arab MK, having served since 1999. He is one of the founders of the Arab Movement for Renewal (Hatenua Ha'Aravit le Hithadshut, or Ta’al) and a member of the Joint List (Hadash, Ra'am, Balad, Ta'al). In 1993, after the signing of the Oslo Accords, Yasser Arafat, then-Chairman of the Palestinian Authority, appointed Tibi as his special adviser. Since his election to the Knesset, Ahmad Tibi has managed to pass 12 laws, most of which focus on social, economic and consumer issues. In 2010, Tibi gave a speech about the Holocaust, which then-Speaker Reuven Rivlin called “the finest speech ever given in the history of the Knesset”.
