Tripoli , Libya ( CNN ) -- Libya 's National Transitional Council will hold an urgent meeting Sunday to discuss the formation of an interim government , a senior council member told CNN Friday . Mohammed Naser , the council member , said the formation of a government could take up to one week , but NTC members agreed that the interim government would include a premier , a vice premier , and 22 ministers . Naser did not give further details . Earlier this week , Elamin Belhaj , a senior member of the NTC , told CNN the formation of a Libyan government would not be announced until anti-Gadhafi forces controlled the borders of the country and liberated three cities that still remained under loyalist control -- Bani Walid , Sirte and Sabha -- a task that could take up to one month , he said . `` We are not a fully established country , '' he said this week of the fact that Libya has not been completely liberated . The NTC , he said , will expand as cities are liberated in order to give representation to all regions of the country . Ultimately , the council could have approximately 80 members ; it currently has 43 . Belhaj said that after liberation , the NTC will create an interim government by appointing a prime minister who will be responsible for forming the government . The prime minister will decide how many ministers will be in that interim government , but he must return to the NTC for approval of that government . Belhaj explained that the NTC decided to use the expression `` interim government '' because `` the international community wants to deal with us through a government . '' That interim government will prepare for the election within eight months of a National Congress , a body that will have 200 members . At the creation of the congress , the interim government will cease to exist . The National Congress , Belhaj said , will form a committee to write a constitution for Libya , which will then be presented to the Libyan people to vote on in a referendum . If it 's approved , Libya would have a permanent democratic constitution for the first time , he said . In the final stage of transition , Libya will create a political system , including the formation of political parties that will participate in general parliamentary and presidential elections . Asked to comment on charges that the ranks of the NTC are divided by regional rivalries , Belhaj said there is no division in the NTC . Islamists and secularists are `` all together '' during this stage of revolution , he said . CNN 's Mohammed Tawfeeq and Michael Martinez contributed to this report .
