Nepal's party of former communist rebels has agreed to join the Constituent Assembly elected last month, easing a political stalemate in the Himalayan nation.

United Communist Party of Nepal (Maoist) spokesman Agni Sapkota said party members agreed Tuesday to join the assembly after a meeting with leaders of other major political parties. The parties have agreed to form a parliamentary committee to investigate the Maoists' allegations of election irregularities.

The Maoists came third in the Nov. 19 election and immediately threatened to not participate in the new government unless a high-level independent investigation into the polls was ordered.

The new assembly would replace one elected in 2008 that was mired in bickering and failed to write a constitution.
