The conditions set by Bersatu in giving its support for Ismail Sabri Yaakob to be prime minister have caused uneasiness among the Umno leadership, prompting the latter's supreme council to call for a special meeting, according to sources.

"Last night, several Umno leaders had a meeting on this issue. And a special supreme council meeting has been scheduled for tomorrow.

"The party is uneasy, and look at the conditional support by Muhyiddin seriously," a party insider told Malaysiakini.

When contacted, a member of the supreme council confirmed there was a meeting held last night. However, the leader said tomorrow's meeting was still not confirmed.
