The Sarawak state election has shown a swing among urban voters towards BN, said Prime Minister Najib Abdul Razak.

He said the landslide win also builds the momentum for the ruling coalition to face the next general election.

"We will conduct an in-depth study. The big question is whether this is in the direction of GE14.

"... In other words, this victory is something that we can build on. In other words, this is a momentum and we have much work to do to ensure a sterling win in the GE14," he added.

Elaborating on the urban swing, he said this led to DAP losing five out of 12 seats it won in the last polls.

"What we have seen in (in this polls) apart from BN maintaining its traditional strongholds is an urban swing towards BN," he told reporters at the Wisma Bapa Malaysia in Kuching.

He said this also served as a recovery for the BN component, the Chinese-based SUPP, and other parties in the ruling coalition.

"We will strengthen BN as a family, which is good to each other," he added.

Sarawak BN, under the leadership of Chief Minister Adenan Satem, secured a landslide win, taking 72 out of the 82 seats in the state assembly.

Meanwhile, Najib also said the opposition failed to use the GST to dent BN’s performance because the people of Sarawak have accepted the tax because it would be used to develop the economy.

"The opposition failed to get the desired response for the GST issue.

"People here understand the GST was created to develop the economy. It brings development to Sarawak, especially in the construction of the Pan-Borneo highway," he added.

However, the prime minister said the BN victory is shrouded in sadness with regard to the helicopter crash on Thursday, which robbed the lives of Plantation and Commodities Deputy Minister Noriah Kasnon and five others.

"After this, I will head to the hospital to meet the families of the victims," he added.
