In 1975, Mahathir ran for one of the three vice-presidencies of UMNO. The contest was considered a battle for the party's leadership succession, with Razak and his deputy, Hussein Onn, declining health. Each of Razak's preferred candidates was elected: former Chief Minister of Melaka, Ghafar Baba; Tengku Razaleigh Hamzah, a wealthy businessman and member of Kelantan's royal family; and Mahathir. When Razak died the following year, Hussein, as his successor, was forced to choose between the three men to be deputy prime minister; he also considered the ambitious minister Ghazali Shafie. Mahathir's rivals had significant political liabilities: Ghazali, having been defeated by the others for a vice-presidency, lacked the support of UMNO members; Ghafar had no higher education and was not fluent in English; and Razaleigh was young, inexperienced and, critically, unmarried. However, Hussein's decision was not easy. Hussein and Mahathir were not close allies, and Hussein knew Mahathir's choice would displease Abdul Rahman, still alive and revered as the father of Malaysia's independence. After six weeks of indecision, Mahathir was, much to his surprise, appointed as Hussein's deputy. The appointment meant that Mahathir was the anointed successor to the prime ministership.
