Mukhriz Mahathir will take on incumbent Muhyiddin Yassin for the post of president in the Bersatu polls next month.
Muhyiddin, who is also the prime minister, will be challenged by Mukhriz, who is the current party deputy president, and Mohd Faiz Azlee Sham (Cheras Bersatu chief).
Dr Mahathir Mohamad, meanwhile, remains unopposed for the chairpersonship.
