The relationship between leftwing splinter groups and the communists was notoriously bad. The CPH ignored the Revolutionary Socialist Party during its four-year term in the 1930s. The Pacifist Socialist Party, which was partially composed of those expelled from the CPN, was denounced as a party of agents of the U.S. Central Intelligence Agency. The CPN methodically voted against proposals of the PSP, even when they supported them. In the 1980s the PSP and the CPN grew closer as they both campaigned against nuclear armament and both began to embrace New Left and libertarian politics. In 1984 they formed a common list for the European Election together with the green Political Party of Radicals (PPR) and the Greens. In the 1989 the CPN, PSP and PPR were joined by the leftwing Christian Evangelical People's Party in the formation of the GreenLeft.
