Former Nepali prime minister K.P. Oli looks set for a return to power after winning his seat in parliament on Sunday and his Communist UML party and Maoist allies on course to win a majority.
Counting is still under way following an election on Thursday that capped a near-decade long transition after 10-year civil war toppled the country's monarchy in 2006.
The alliance of the Communist Parties of Nepal Unified Marxist-Leninist (CPN-UML) and the Maoist Center (CPN-MC), who formed a coalition in October, are ahead in the two-phase elections to determine 275 members of the national lower house and 650 seats of the seven provincial parliaments.
Final election results are expected to take about a week, election officials said.
Oli, 65, has vowed to form a government that lasts its full five-year term, something no prime minister has achieved since parliamentary democracy was established in 1990.
His campaign has called for the extension of the Chinese railway network into Nepal and implement of hydroelectric, airport and other infrastructure projects to create jobs.
Since the 2006 peace agreement that ended the Maoist-led insurgency against the 240-year-long monarchy, the country's main communist parties have often found themselves at odds.
According to analysts, the newly-formed alliance could provide the political stability necessary for significant economic development.
“We can expect Oli to lead a stable government with the Maoists as strong allies,” said Bipin Adhikari, a constitutional expert. “Once there is political stability he can implement a development agenda and attract foreign investment."
