The Sam Rainsy party (SRP) said it should get leadership positions in the new national assembly.
Currently the nine committees are divided between the Cambodian People's Party (CPP) and the FUNCINPEC party.
Mr. Keo Remy of the SRP party said the SRP should chair at least one committee in the national assembly.
A FUNCINPEC official who asks not to be identified said the SRP was given a chance to chair a committee but it refused to accept.
