Who were the Cambodian National Unity Party? In essence they were the continuation of the Communist Party of Kampuchea, or as they are more commonly known the Khmer Rouge.
The Khmer Rouge ruled Democratic Kampuchea under the guise of the Communist Party of Kampuchea, which followed an extremely warped version of Marxism-Leninism-Maoism, or just bat shit crazy Polpotism, depending on your take on things.
After their overthrow and the setting up of the Collation Government of Kampuchea (internationally recognized) they morphed into the Party of Democratic Kampuchea , still run by Pol Pot, but now espousing democratic socialism.

In 1992 as the country was readying for elections the party again changed its name, this time to the Cambodian National Unity Party. Whilst it did not post much of a platform one can assume it was at least part agrarian socialism and part ultranationalism.
After deciding not to participate in elections and to continue its civil war the party was led by the relative moderate Khieu Samphan from their bases in Pailin and Anlong Veng.
Khieu Samphan and Ieng Sary eventually defected to form their own parties, from which time the rebel government and the party were led by strongman Ta Mok.
Pol Pot was to order the killings of both Ta Mok and Son Sen, the later of which was successful, the former not. Ta Mok had Pol Pot put on house arrest before he died in 1997, of natural causes.
In the 1998 the last government of the Khmer Rouge and their political wing, the Cambodian National Unity Party were disbanded.
Ta Mok remained on the run in the jungles around the Thai border until 1999 when he was finally captured alongside some party loyalists.
Ta Mok dies before ever facing justice for crimes….
