With only four days left to go before polling day, the battle for support in the Sibu by-election has shifted to a higher gear and local issues are now taking centre stage in campaigning.

The Sarawak United People's Party (SUPP), the Barisan Nasional's (BN) component party fighting the by-election, today fired a salvo against the "enemy" DAP and demanded to know what the peninsula-based party had done for the people of Sibu.
