Parti Sosialis Malaysia (PSM) will not be joining Pakatan Rakyat as a component party but has instead opted to continue its “close cooperation” with the opposition coalition in the fight to topple the BN-led government.

PSM secretary-general S Arutchelvan said the decision followed a spirited discussion between two camps in PSM – one in favour of joining Pakatan, and another dead set against it – in a special closed-door session that dragged on until 2am last night that resulted in the compromise.
