GE13 WATCH Given that incumbent Wong Ho Leng will not defend the Sibu parliamentary seat on grounds of illness, the DAP can expect an all-out fight from rivals in Sarawak.

The Sarawak United People's Party (SUPP) is expected to field a heavyweight - Vincent Lau, 65 - in its bid to reclaim the seat lost by a slim majority of 398 votes in the 2010 by-election.

Vincent will face Oscar Ling, a 36-year-old pharmacist and Wong’s special assistant, who was named last month as the DAP’s candidate.
