Yemen
In South Yemen the local ANM branch was instrumental in forming the National Liberation Front which would later become the Yemeni Socialist Party (YSP), the leading political party in the Peoples Democratic Republic of Yemen. In North Yemen, the members of ANM broke away from the mother organization in June 1968, forming the Revolutionary Democratic Party of Yemen (which would eventually merge into the YSP).
After the reuniting of the two Yemens in 1990, the YSP became the major opposition party in the Republic of Yemen.
