KUALA LUMPUR – However despite Mahathir’s recent outbursts on social media about the 1MDB allegations and his criticism of Najib, the incumbent appears to have the backing of the United National Malays Organisation (UMNO), the main party in Malaysia’s ruling coalition. UMNO Secretary General Adnan Mansor said that the party was holding together, despite rumors of a split over Najib’s position. Mahathir, who celebrated his unofficial 90th birthday on Friday, remains an influential figure in party circles and continues to call for Najib’s ouster. “UMNO is intact. We are united behind the prime minister to protect his [party] presidency. For those who wish to see UMNO disintegrate, it will not happen,” Adnan said, speaking at the iftar event attended by Najib.
