The government will increase the goods and services tax (GST) to at least 10 percent if the BN wins big in the Sarawak state election, claimed Sarawak DAP chief Chong Chieng Jen. .

He said this was due to the fall in crude oil prices and the subsequent loss of government revenue.

"The coming Sarawak election will be a test of the peoples' acceptance of the GST; it will be the time for Sarawakians to oppose the GST through their votes.
