Kayed al-Ghoul, a member of PFLP's political bureau, made the remarks in an interview with "Voice of Palestine."

"Haneya seeks a national unity which enables all Palestinian parties to join a national government that empowers Palestinians to face international force," said al-Ghoul.

His comments came one day after Haneya told representatives of Palestinian factions excluding Fatah that he is still willing to form an expanded coalition government.

However, al-Ghoul said he didn't expect Haneya to adopt political agenda of the Palestinian Liberation Organization (PLO), which Hamas denied as the sole representative of the Palestinian people.

Earlier, al-Ghoul said that Hamas' refusal to recognize the PLO as the only legitimate representative of all Palestinians was the reason why the PFLP refused to join the Hamas-led cabinet.

Hamas, which is sworn to Israel's destruction, is facing heavy financial and diplomatic pressure from the U.S. government, the EU and Israel because it refuses to recognize Israel, renounce violence and accept previous agreements.
