Voters dealt Singapore's ruling People's Action Party its third electoral setback in a year, allowing the opposition to hold onto a Parliament seat in a by-election Saturday. According to AP, Workers' Party candidate Png Eng Huat, a 50-year-old businessman, won 62 percent of about 21,700 votes cast in Hougang district while PAP candidate Desmond Choo received 38 percent, election officials said. The PAP still controls 81 of 87 parliamentary seats, but it has struggled to staunch growing discontent over a surge in foreign workers, soaring housing and transport costs and stagnant salaries for low-wage earners. Prime Minister Lee Hsien Loong and other PAP leaders campaigned frequently for Choo during the nine-day campaign.
