Nigeria Vows Delayed Poll Will be Held Monday VOA News April 03, 2011 An election officer in Nigeria's commercial capital, Lagos, makes a phone call after the postponement of parliamentary elections, April 2, 2011 Photo: Reuters An election officer in Nigeria's commercial capital, Lagos, makes a phone call after the postponement of parliamentary elections, April 2, 2011 Nigerian election officials have vowed to hold parliamentary elections on Monday, after the vote, set for Saturday, was abruptly postponed as voters stood in line. Nigerian officials blamed the delay on supply companies who they said failed to get ballots and tally sheets to polling stations on time. Members of the Independent National Electoral Commission said Sunday that all needed materials had arrived at polling stations. Election officials were set to meet with party officials and candidates on Sunday to discuss the situation. The postponement sparked anger and disappointment across Africa's most populous nation. This month's elections are widely seen as a test of Nigeria's ability to hold free, fair and credible elections. The last polls in 2007 were badly marred by violence, fraud and disorganization. Nigerians are set to vote in three separate polls this month to elect a new parliament, president, and 36 state governors. The parliamentary election will be followed by a presidential vote on April 9 and state polls on April 16. Nigeria's ruling People's Democratic Party is hoping to retain control of the presidency and parliament. President Goodluck Jonathan is facing a field of challengers led by former military ruler Muhammadu Buhari. Jonathan is seeking his first full term after rising to power last year following the death of predecessor Umaru Yar'Adua. His run was opposed by some PDP members who accuse him of breaking an informal rule to rotate the presidential nomination between Muslims from the north and Christians from the south. Jonathan is a Christian, while Yar'Adua was a Muslim. President Yar'Adua died just three years into what was expected to be a two-term, eight-year presidency. Nigeria's population of 140 million - the largest in Africa - is split roughly evenly between Muslims and Christians. Some information for this report was provided by AFP and Reuters. .
