Umno Youth chief Khairy Jamaluddin said Sarawakians voting for the opposition out of anger in the May 7 polls will not contribute to development in the state.

"Because (if voters) vote for the opposition because they are dissatisfied or angry (at the government), it will not have any results in the context of Sarawak's development," he said after officiating BN Youth's election operations centre in Kuching today.
