KHARTOUM, Oct. 3 (Xinhua) The Sudanese President Omer al Bashir Saturday called on all Sudanese people to work together for north- south unity to pave the way for a referendum on self- determination for southern Sudan in early 2011. Addressing the concluding session of the ruling National Congress Party (NCP), al Bashir said 'dividing Sudan will harm the future of the country and negatively affect the whole continent, and therefore everybody should work to surpass this phase and preserve unity of Sudan.' 'We want Sudan to remain as we have inherited it from our ancestors. We want it to be united in its north and south. However, this does not mean we have withdrawn from the right of self- determination for the sons in southern Sudan, because it is a political and constitutional commitment' added al Bashir. The Sudanese President renewed the commitment of government and the NCP to end the Darfur conflict, saying 'we will make all possible efforts to reach a comprehensive peace in the Darfur region, end the suffering of its citizens and restore the stability and security there.' The NCP Saturday concluded its 3rd general conference with the election of President Omer al Bashir as the party Chairman for four years and approved his nomination as the party candidate for the presidential elections in April 2010. The NCP has approved 25 percent for the representation of women in all the party institutions together with the party Statute, recommendations and state nominees for the membership of the party 's national shura (consultative) council.
