A leader of Fatah's young guard, he is pushing for a generational change in the movement.
Israel has said it will not grant him early release, although there is persistent speculation that he would be freed in the right political context.
MUHAMMAD ABU ALI YATTA, 50, second on the Fatah list.
He has been in Israeli prison for 26 years, sentenced to life for killing an Israeli settler. He has not previously occupied any position in Fatah, and is believed to have been put on the list as a gesture to the thousands of Palestinians held by Israel. He is among the longest-serving inmates.
INTISSAR AL-WAZIR, 64, long-time leader of the Palestinian women's movement.
Has been welfare minister since 1996 and is the widow of Khalil al-Wazir, the military chief of the Palestine Liberation Organisation who was killed in an Israeli commando raid in Tunis in 1988. She has been a member of the Palestine National Council since 1974.
ISMAIL HANIYA, 46, the top Hamas candidate.

MUHAMMAD ABU TAIR, 55, second on the Hamas list.
Spent 25 years in Israeli jails. He is from Jerusalem, and is a former member of Fatah and of the Popular Front for the Liberation of Palestine-General Command.

HANAN ASHRAWI, 59, Christian, emerged as a prominent figure in Palestinian politics during the first intifada, which erupted in 1987.
Eloquent and often feisty, she was official spokeswoman for the Palestinian delegation to the Middle East peace talks from 1991-93, and headed a committee responsible for Jerusalem's citizens rights after the signing of the peace agreement.
Ashrawi quit her minister's post
to protest against graft
