Mr PALMER (Fairfax) (14:23): My question is to the Prime Minister. Does the government plan to introduce optional preferential voting in the Senate elections, which will guarantee 38 senators and eliminate most of the crossbench, so the government can require the crossbench to pass all government legislation or threaten them with an early election? Will this mean the government, with crossbench support, can introduce optional preferential voting in the House of Representatives?
