UCPN(Maoist) party said on Thursday that it will not join the new CA, citing conspiracy and irregularities in Tuesday's Constituent Assembly(CA) election. The move is believed to deepen political crisis in the Himalayan nation.

The party called a press conference and announced that if Election Commission fails to review and cancel the vote counting they will not participate in the new CA election.

As the vote counting is underway across the nation, UCPN ( Maoist) party that secured first position with overwhelming majority in 2008 is in third position in more than 150 constituencies out of 240.

"We are ready to respect people's mandate. But it does not mean that we should accept all conspiracies and irregularities launched against us," Party Chairman Pushpa Kamal Dahal Prachanda said in a press statement.

Dahal, a former prime minister, also lost second CA election from his Kathmandu- 10 constituency. The Maoist party, however, said that it is committed to 12-point understanding signed in 2005 and Comprehensive Peace Agreement in 2006 that brought the former Maoist rebels in the peaceful politics.

"The whole election process should be reviewed. We are ready to settle the disputes in a peaceful way," he said.

In the vote counting so far, Nepali Congress is leading across the country while CPN-UML is in second. The UCPN (Maoist) which became largest party in 2008 election is in third across the country. The UCPN (Maoist) that gained 120 seats out of 240 is leading only in one and half-dozen constituencies.

Other parties, however, said that Maoist is demanding the voting process be canceled as the party is losing election across the country. "We lost election in 2008 but we accepted the mandate. So Maoist should respect the people's mandate," Nepali Congress President Sushil Koirala said in a press statement.

Meanwhile, UN Secretary-General Ban Ki-moon congratulated the people of Nepal for the peaceful and successful election. "The turnout shows their determination to take the peace process forward," Ban said in a press statement.
