VIENTIANE, Dec 30 — Laotian lawmakers overwhelmingly voted into office a new prime minister after the country's former leader stepped down over health concerns, state media reported today.

Sonexay Siphandone, Laos's former deputy prime minister, took leadership of the communist nation with 149 of 151 national parliamentary votes.

"I will raise the revolutionary spirit to a higher level," Siphandone told the country's parliament as he accepted the role.

Former prime minister Phankham Viphavanh had offered his resignation to the National Assembly earlier today, citing health concerns.

"When the country is faced with more difficulties, I'm not able to handle this hard duty anymore," said the 72-year-old, who took office in March last year.

The reclusive country has been hit by tough economic problems this year, battling fuel shortages and soaring inflation. — AFP
