The outcome of Ghana’s presidential run-off is too close to call and will be decided by voting on Friday in a single constituency where balloting has yet to take place, the electoral commission said on Tuesday.

In a twist to what was already a tense and closely fought race, the commission said the outstanding vote in the Tain constituency would determine the final result of the election in the West African state, the world’s No. 2 producer of cocoa.

With votes counted from 229 of the 230 constituencies, John Atta Mills of the opposition National Democratic Congress (NDC) held a slender lead with 50.13 per cent of the votes, while Nana Akufo-Addo of the New Patriotic Party (NPP) had 49.87 percent.
Only 23,050 votes separated the two.
