Goodluck Jonathan, Nigeria's new president, who was sworn into office just days ago, is set to nominate a vice-president early next week for Africa's most populous nation.
But geopolitical divisions are expected to play a vital role in the nomination due to an unwritten rule of power balance between the predominantly Muslim north and majority Christian south.
The ruling People's Democratic Party has long maintained a geopolitical zoning system for choosing their leadership.
And now all eyes are on Jonathan, a Christian, as he prepares to choose a deputy.
