"The referendum will boost the political and parliamentary life and will help get out of the current crisis," Taisser Khaled said, adding that the referendum "doesn't contradict with the parliamentary life."

He criticized Hamas for opposing the referendum idea, accusing some Hamas leaders of "creating troubles" by claiming the referendum as illegal.

Abbas has said that he would order a referendum if the inter-Palestinian dialogue fails to adopt the National Accordance filed by Palestinian prisoners in an Israeli jail.

The prisoners' document calls for the establishment of an independent Palestinian state on the territories occupied by Israel in the 1967 Arab-Israeli war.

It also calls for forming a national unity government. Khaled said that the referendum would have no relation to the results of the January legislative elections.

Hamas, which swept the January elections and took office in late March, refuses Abbas' intention for such a referendum and justifies its refusal by considering the referendum as a bid to "turn around the results of the elections."
