Liberia’s ex-Finance Minister Ellen Johnson-Sirleaf is on the brink of becoming Africa’s first elected female president as voting returns gave her what looks like an unassailable lead in the presidential run-off. The National Elections Commission said on the basis of votes counted thus far Johnson-Sirleaf has 59.2 percent while rival, former footballer George Weah, has 40 percent.However, Weah claimed the ballot was full of irregularities. He says he has substantial evidence of election fraud. The accusations threaten to mar what had been a trouble free election. The poll is the first to be held since the end of a 14-year civil war that decimated Liberia’s economy and left quarter of a million people dead. The electoral commission and international observers said they were investigating Weah’s complaint, but continued to issue regular voting results.
