Parti Sosialis Malaysia (PSM) may consider joining the opposition coalition if it agrees to the party's manifesto.
PSM secretary-general S Arutchelvan said, "We will support the Pakatan Rakyat in both the state assembly and parliament.
However, if the coalition puts forward motions which are against the principles of PSM, "we will oppose strongly," he said while talking to reporters after the annual asset declaration ceremony today at Chinese Assembly Hall.
He added that although currently cooperation with the Pakatan Rakyat is minimal, PSM may join forces with the former in future if it is willing to struggle for free higher education and fight against the privatisation of hospitals.
