Parliamentary democracy in Malaysia has been continuously undermined through gerrymandering (manipulation of electoral composition) and malapportionment (manipulation of electoral size). A clear example of malapportionment is how in the March 2008 elections, Putrajaya, with a population of about 5,000, sent one MP to Parliament while my constituency, Seputeh, which has over 76,000 voters, also had only one seat in Parliament.
If you consider the March 2008 elections, Barisan Nasional (BN) obtained barely half of the popular vote — about 51% of the 7.9 million votes cast and yet they controlled 63% of the seats at stake in Parliament, i.e. 140 out of 222 seats. If you exclude the voters in Sabah and Sarawak, where BN won all but two seats, their popular vote dips to 49.8% in Peninsula Malaysia. (Source:http://www.irrawaddy.org/article.php?art_id=10778)
