Weah supporters

Members of the party of Liberian presidential candidate George Weah have threatened to boycott parliament to protest alleged fraud in last week's presidential run-off.

The lawmakers-elect from the Congress for Democratic Change issued a statement Monday vowing not to take their 18 legislative seats if Mr. Weah's complaints of fraud are not addressed.

They won their seats in Liberia's first post-war general elections last month.

The National Election Commission says it will hear Mr. Weah's complaints starting on Tuesday.

Hundreds of Mr. Weah's supporters marched peacefully through the capital, Monrovia, Monday.

Former Liberian Finance Minister Ellen Johnson-Sirleaf won about 60 percent of the vote, to 40 percent for Mr. Weah, a former soccer (football) star.

International observers say there is no evidence of widespread fraud. And leaders from several African countries praised the run-off as peaceful, transparent, free and fair.
