Police have revoked its approval for a debate between former prime minister Dr Mahathir Mohamad and Tourism and Culture Minister Mohamed Nazri Abdul Aziz, less than 24 hours after giving its nod, according to the organiser Kumpulan Media Karangkraf.

The company’s managing director Hussamuddin Yaacub this evening took to Twitter to share a letter from the Shah Alam district police headquarters informing them that the approval had been revoked.

“Strange. The dialogue between Mahathir and Nazri - yesterday we received a letter approving the permit. This evening the permit was revoked,” he said.
