JUBA, Sudan (Reuters) - South Sudanese have voted overwhelmingly to declare independence from the north in a referendum held last week, according to early figures and a Reuters survey of officials in nine of the regions 10 states. Referendum officials reported on Wednesday that votes to secede approached 99 percent in some southern states and disapora communities in Egypt, Ethiopia and Kenya. Southern leaders have urged people from the oil-producing territory to wait until official figures due in early February before celebrating, for fear of antagonizing the north. The figures are in line with expectations for the plebiscite, the climax of a 2005 peace deal that ended decades of north-south civil war. Referendum officials told Reuters of large votes in favor of independence in the southern states of Central Equatoria, Unity, Lakes, Jonglei, Warrap, Western Bahr al-Ghazal, Northern Bahr al-Ghazal, Eastern Equatoria and Upper Nile. Central Equatoria state, a territory that includes the southern capital Juba, reported 449,290 votes for separation and just 4,985 votes for unity. Campaign banners in Juba described the vote as a last march to freedom after decades of war and perceived northern oppression. International observers this week said the vote was credible, removing another possible hurdle. A total of 153,839 people voted for independence in Western Bahr al-Ghazal state, against 7,237 for continued unity with the north, the states committee chairman Wol Madut Chan told Reuters. Western Bahr al-Ghazal lies on the souths border with the north, neighboring the strife-torn Darfur region. Its figures amounted to a 95 percent vote for separation, once spoilt and unmarked ballots were included. In Lakes State, referendum committee chairman Michael Mabor Makuel Awur said preliminary figures were 227 people for continued unity with the north against 298,216 for separation - or more than 99 percent. Referendum officials in Eastern Equatoria and Upper Nile states said they were also heading toward a 99 percent vote for separation. Warrap, Northern Bahr al-Ghazal and Jonglei states released incomplete figures showing similar majorities. Michael Moyil Chol, the chair of the referendum committee for oil-producing Unity state, which also borders the north, said: So far it looks like more than 80 percent are in favor of independence. Officials did not release figures or give any indications in the state of Western Equatoria.
