The decision was made following a request from the CPP, which won all 125 parliamentary seats in the election.
Earlier, PM Hun Sen said that a new government will be set up on September 6, one day after the first session of the 6th National Assembly.
According to the official results announced by the National Election Committee (NEC), the CPP garnered more than 4.88 million votes, or 76.85 percent, of the total valid votes.
This is the first time the CPP has swept up all seats in the parliament since the election in 1993, thus opening up opportunities for the Party to make major decisions and policies for the country over the next five years.
Hun Sen, 66, who has been in power for 33 years, will continue to lead the Cambodian government for another five years.-VNA
