The People's Action Party has won every election since self-government in 1959. The dominance of the PAP, coupled with a low level of press freedom and restrictions on civil liberties and political rights, has led to Singapore being classified by some as a semi-authoritarian regime. One of the five founding members of ASEAN, Singapore is also the host of the Asia-Pacific Economic Cooperation (APEC) Secretariat and a member of the East Asia Summit, Non-Aligned Movement and the Commonwealth of Nations.
