Ex-football superstar George Weah has been announced as the winner of Liberia's presidential run-off, beating Vice President Joseph Boakai in the first democratic transfer of power in decades following two devastating civil wars. Weah is set to replace incumbent Ellen Johnson Sirleaf, who took over at the helm of Africa's oldest republic in 2006. <br/><br/>The National Election Commission (NEC) said Weah had won an insurmountable 61.5 per cent of Tuesday's vote, which was delayed several weeks after a legal challenge from Boakai. The NEC said that with 98.1 percent of all votes counted, Boakai had secured only 38.5 percent support.
