Barisan Nasional
By the practice of the past ruling coalition Barisan Nasional, where the United Malays National Organisation (UMNO) was the unofficial leader, the UMNO Deputy President was usually appointed the Deputy Prime Minister by the Prime Minister (who was the UMNO President). In the organisational structure of Barisan Nasional, the President and Deputy President of UMNO were automatically made the Chairman and Deputy Chairman of Barisan Nasional.
