The by-election was widely known as the "Battle of the Mighty
Rejang" and was seen as a litmus test for the popularity of the opposition
Pakatan Rakyat and governing Barisan Nasional coalitions on a including land rights, poverty, native displacement and unemployment in
Sarawak. One of the main issues during the election was
the ban of the use of the word 'Allah' in Christian publications. However, the Sarawak police has banned political parties from using the issue during campaigning in the by-election as it was deemed to be a sensitive issue. Sarawak's Officer in Charge of Criminal Investigations, Huzir Mohamed, threatened to prosecute offenders of the ban under the
Sedition Act or the
Internal Security Act (ISA).
Barisan Nasional The
Barisan Nasional did not initially release a policy manifesto for the by-election, but sought support on the basis of its claim to have caused Sibu's economic growth and development. Nevertheless, late in the campaign, the BN-SUPP candidate, Robert Lau Hui Yew, himself released a manifesto in which, according to
Bernama, he mentioned that he would prioritise ''"getting more investment, job creation, skills training for single parents to increase their income, install more CCTVs in town to improve security and reduce street crimes rates as well as to transform Sibu into a 'wireless' township."'' During the campaign period, Prime Minister Datuk Seri Najib Tun Razak had distributed
RM18 million to 60 Chinese aided primary schools, five independent Chinese secondary schools and two missionary schools in Sibu. Najib said that the Barisan Nasional government would continue to do more for Chinese education in the country, saying that
"the Barisan government is a true friend of Chinese education," when addressing more than 3,000 Chinese educationists. Besides that, some 246 families living in an under-developed region in Sungai Igan within the constituency had received a total of RM147,600 as a one-off allocation from the Federal Government. Four
Methodist churches in town had been given special grants totalling RM1.75 million from the BN federal government in the final hours of the by-election campaign. The SUPP attacked the DAP on the basis of its coalition with the Islamist PAS, arguing that "A vote for Rocket is a vote for Islamic State".
Lim Kit Siang, the parliamentary leader of the DAP, said that the issue was a "killer weapon" which could "finish off" the chances of DAP's candidate winning by frightening off the Chinese and non-Muslim voters in Sibu as it did during the
1999 Malaysian General Election where both
Karpal Singh and Lim himself lost their parliamentary seats. The SUPP also claimed that if the DAP was to be voted in
kampua noodles could no longer be sold as they were mixed with pork lard; a reference to PAS's policy to establish Malaysia as an Islamic state.
Abdul Taib Mahmud, the BN chief minister of Sarawak, revised new land renewal rates which took effect on June 1. He said that the Sarawak new land rates is the cheapest in Malaysia as compared to other states. In accordance with opposition proposal for the unconditioned, automatic renewal of land leases, he also challenged the opposition-led state governments to announce new land rates lower than the current one announced by himself, without risking the income of the state governments.
Najib Tun Razak, the
Prime Minister and leader of BN, promised voters in Rejang Park, a DAP stronghold, 5 million ringgit to alleviate floods if SUPP's Robert Lau Hui Yew won the seat, stating at an election appearance:
"Do we have a deal or not? We do! You want the RM5 million, I want Robert Lau to win.” Democratic Action Party The DAP set out a seven-point manifesto with the theme "Sibu Jom Ubah" or "Sibu4change" for the by-election campaign and on the top of it is solving the town's flood woes in two years when the party and its coalition becomes the government at the federal and state levels. Another point in the manifesto stated that DAP would provide all Sarawakians aged above 60 a minimum of RM100 per annum as a gift for their contributions to the state. Wong also promised that if elected, he would call upon the Prime Minister and Home Minister to immediately cease the legal dispute with the Christian churches over these matters to protect the freedom of religion in Malaysia for non-Muslims. The DAP has also challenge candidate Robert Lau to make his stand about the ban on non-Muslims using the word "Allah" with DAP MP
Teresa Kok stating that
"If Robert Lau intends to be a Member of Parliament that speaks up for a Christian-majority constituency, Sibu, then he has the moral duty to declare his stand on this thorny issue, so that the voters in Sibu can decide whether they can count on him to speak up on this issue," Another issue that was brought up during the by-election was the decision of the Home Ministry to destroy the 5,000 copies of Indonesian Bibles confiscated. On SUPP's questioning DAP's association with PAS despite having different ideology, the DAP defended itself by stating that PAS has been steadfast in the rights to freedom of religion of non-Muslims and this can be seen through PAS being able to declare that there is absolutely nothing in the Quran which forbids the use of the term "Allah" in Christian publications. The DAP, through its leader
Lim Kit Siang also pressured Hui Yew to speak up against the government's education policy, claiming that Hui Yew's choice to have his children educated overseas demonstrated his lack of confidence in Malaysian education. On education, the DAP also criticised SUPP's involvement in the sale of the Laila Taib College, previously known as United College Sarawak, to the Yayasan Sarawak (Sarawak Foundation) for the price of one
ringgit, when the local Chinese population had donated money to fund the college's building. ==Results==
