At least three senior party leaders are widely expected to be dropped from the central working committee of the Sarawak United People's Party (SUPP) at the party's triennial delegates conference this weekend.

They are vice-president Song Swee Guan, who is also member of Parliament for Kuching, vice- president William Tanyuh, a former state representative for Bengoh, and deputy secretary-general Noel Ramsay Jitam, a former assistant minister.

Song's party seat is expected to go to Works Ministry parliamentary secretary and member of Parliament for Padawan Yong Khoon Seng while Tanyuh's will either go to the member of Parliament for Serian, Richard Riot, or the state assemblyperson for Bengoh, Dr Jerip Susil.
