Liberia's election commission on Friday confirmed its rejection of fraud allegations over the first round of presidential elections, setting the scene for a showdown at the Supreme Court.

The announcement, which concerns the October 10 vote, confirms a decision initially taken on Monday, National Elections Commission (NEC) official Davidetta Lassana told reporters.

A second round of voting, pitting Joseph Boakai of the ruling Unity Party against former footballing superstar George Weah, had been due to take place on November 7 but was postponed by the Supreme Court following a complaint about electoral fraud.
