On 25 May 2009 during a debate in Parliament, Siew Kum Hong called for a hybrid Parliament in which a limited number of seats would be allocated by way of proportional representation, while the majority would still be filled the way they are now. He felt this would allow for more diverse views in Parliament, adding that it would be "more consistent with democratic principles than a scheme like the Nominated MP scheme". Siew also noted that while the act of voting was key to democracy and political participation, a large number of Singaporeans do not get to vote at each election because walkovers are prevalent.
