Umno leaders have spoken out against former Umno Youth chief Khairy Jamaluddin who predicted the party will lose more than 50 percent of its Malay voter base in the upcoming state elections.

Umno supreme council member Mohd Puad Zarkashi said it is baseless for Khairy to assume that Umno will lose those votes due to the long-time anti-DAP brainwashing.
