Liberian opposition presidential candidate Winston Tubman is demanding pre-conditions for next month's runoff election against President Ellen Johnson Sirleaf.

Tubman tells VOA that the conditions include removing elections commission head James Fromayan.

Tubman says many members of his Congress for Democratic Change party think Fromayan is biased in favor of the Sirleaf government and dismissive of their concerns.

Fromayan has called the accusations of bias unfair. But Tubman says his party believes the runoff has to be carried out in a manner that is less controlled, and that the commission must be more objective. He says the CDC has no plans to boycott the runoff if its demands are not met.

Tubman is a former Liberian justice minister. He and President Sirleaf were the top two finishers in the October 11 presidential election. No candidate won enough votes to avoid the November 8 runoff.
