Since its inception the Alliance remained a coalition of communal parties. Each of the component parties operated to all intents and purposes, save that of elections, as a separate party. Their membership was communal, except perhaps Gerakan, and their success was measured in terms of their ability to achieve the essentially parochial demands of their constituents.[3]
Although both the Alliance and Barisan Nasional registered themselves as political parties, membership was only possible indirectly through one of the constituent parties. In the Alliance, one could hold direct membership, but this was abolished with the formation of the Barisan Nasional. The Barisan Nasional defines itself as "a confederation of political parties which subscribe to the objects of the Barisan Nasional". Although in elections, all candidates stand under the Barisan Nasional symbol, and there is a Barisan Nasional manifesto, each individual constituent party also issues its own manifesto, and there is intra-coalition competition for seats prior to nomination day.[4]
In 2008, the Sabah Progressive Party (SAPP), consisting of two MPs, announced it would leave Barisan Nasional to sit on the crossbenches of Parliament.[5]
As of August 2009, Barisan Nasional's member parties are: * United Malays National Organization (UMNO) * Malaysian Chinese Association (MCA) * Malaysian Indian Congress (MIC) * Malaysian People's Movement Party (GERAKAN) * People's Progressive Party (PPP) * Parti Pesaka Bumiputera Bersatu (PBB) * Sarawak United People's Party (SUPP) * Parti Bersatu Sabah (PBS) * Liberal Democratic Party
