ABUJA, Nigeria—President Muhammadu Buhari took an early lead on Feb. 25 in initial official results from Nigeria’s presidential election but the party of his main challenger quickly rejected the tallies as “incorrect and unacceptable”.
The Feb. 23 election, which U.S. observers said had lost some credibility after being abruptly delayed by a week by officials citing organizational glitches, was expected to be Nigeria’s tightest since the end of military rule two decades ago.
