PETALING JAYA: Former DAP politician Hew Kuan Yau (pic), popularly known as "Superman", may have flown into another controversy by likening Tun Dr Mahathir Mohamad to a "keris" that can be used to eliminate Umno.
In a Facebook posting accompanied by an image of a keris, he quoted from a Chinese saying: "If you want to carry out a task, you have to sharpen your tools".
