Opposition leader Anwar Ibrahim has rejected the new Malay-Muslim-based coalition led by former premier Dr Mahathir Mohamad.

Addressing the formation of the coalition, he pointed out that Mahathir had 22 months to help the Malay-Muslim community.

"I don't support such an initiative because if he really wants to defend Malay-Muslims, in his 22 months (as prime minister for the second time), he should have helped."
