In 1981, Hussein resigned as Prime Minister due to ongoing health concerns and Dr. Mahathir succeeded him. Instead of sticking to the original agreement he had made with Razaleigh, Dr. Mahathir declared an election for the Deputy Premiership - to be decided through the results of the UMNO Deputy Presidency. The new Prime Minister announced that he would not endorse any candidate and would be taking a neutral stance. Razaleigh sensed that Dr. Mahathir was averse to having him as his Deputy per their earlier understanding, but welcomed this decision nonetheless. His main quibble being about how this was not in accordance with tradition (Deputy Prime Ministers are usually hand-picked by the Prime Minister). Razaleigh joined the contest, and his main opposition was Musa Hitam. Eventually, Musa won the election with 722 votes to Razaleigh's 517, becoming the new Deputy President of UMNO and leading to his appointment as Deputy Prime Minister. Razaleigh blamed himself for taking "a rather passive stance" and not having a campaign strategy.
