With Umno backing for Anwar, Langkawi MP Dr Mahathir Mohamad stressed that rime Minister Muhyiddin Yassin's two-seat majority in the Dewan Rakyat had truly evaporated.
The former premier has repeatedly opposed and disputed Muhyiddin's prime minister-ship.
Yesterday, Muhyiddin stressed he was still in power and challenged Anwar to prove his claim.
Anwar has thus far declined to reveal the exact number of MPs on his side, explaining that this information was reserved for the Agong's ears.
