Boevé joined the Dutch secret service in 1955 after attending 5th World Festival of Youth and Students in Warsaw. Prior to the MLPN's creation, he served as the international secretary of the Marxist-Leninist Centre of the Netherlands (MLCN), using his position to create contacts in China and Albania. He also started his own publication, "De Kommunist", in 1966, against the wishes of his MLCN comrades. He was subsequently expelled from the party and formed his own League of Marxist-Leninists in the Netherlands ("Liga van Marxisten-Leninisten in Nederland") in 1968. A year later, this party changed its name to the MLPN.
