Prime Minister Dr Mahathir Mohamad, who was infuriated over the Johor executive council reshuffle, had considered stepping down, according to a source.

The source said the Bersatu chairperson revealed this during the party's supreme council emergency meeting on Monday night.

"He was disappointed and taken aback because the new menteri besar (Dr Sahruddin Jamal) did not follow his advice to keep the cabinet as it is," the source told Malaysiakini.
