Opposition leader Rainsy returns to Cambodia to lead party's challenge to election results

Cambodia's opposition leader has returned from abroad to lead his party's challenge to last month's election results.

Cambodia National Rescue Party leader Sam Rainsy's return Friday from the United States could accelerate resolution of the country's political standoff, which many fear may lead to violent confrontations.

The opposition has threatened to hold a mass demonstration if an impartial committee does not resolve complaints over alleged massive election irregularities. Prime Minister Hun Sen's government responded by deploying troops and armored vehicles into the capital to keep order.

The official election results support the claim of Hun Sen's Cambodian People's Party to have won have won 68 of the 123 seats in the National Assembly. Ratification of the results will not take place until sometime before Sept. 8.
