In 1987, Tengku Razaleigh challenged
Mahathir Mohamad for the presidency of
UMNO. Musa Hitam, who was then having a growing rift with Mahathir, resigned as Deputy Prime Minister, citing irreconcilable differences with Mahathir. He then joined Razaleigh's Team B as UMNO deputy president candidate. In the election, Dr. Mahathir and his Team A managed to retain his position and power over the party. However, UMNO was split into two separate entities as Tengku Razaleigh was left unsatisfied with the result. The split forced the Malaysian court to declare
UMNO as illegal. Shortly after the court ruling, Dr. Mahathir reestablished UMNO as UMNO Baru (New UMNO), though the new UMNO was badly weakened. Tengku Razaleigh at the same time went on his own path and found a new political party called
Semangat 46 in 1989. The number 46 refers to the year UMNO was founded. Musa, however, decided to retire from politics and has not joined the fray since. Between 1990 and 1991, he was Malaysia's Special Envoy to the
United Nations, and since 1995 he has been the Prime Minister's Special Envoy to the Commonwealth Ministerial Action Group (CMAG). Tan Sri Musa also led the Malaysian delegation to the UN Commission on Human Rights from 1993 to 1998 and was elected Chairman of the 52nd Session of the Commission in 1995. As a member of UMNO, Musa has held various positions within the party up to Deputy President until 1987. He also served as the Chairman of
Suhakam, the Malaysian Human Rights Commission, from 1999 till 2002. In 2007, Musa became the chairman of
Synergy Drive Berhad, the entity which arose out of the newly formed merger between
Sime Darby,
Guthrie, and
Golden hope Plantations. He also serves on the International Advisory Council of the
Brookings Doha Center. Musa is currently the Chairman of the World Islamic Economic Foundation. On 25 September 2024, Tun Musa Hitam appointed as the Grand Chancellor of the
Order of Loyalty to the Crown of Malaysia by
Yang di-Pertuan Agong for three year-tenure, until 12 September 2027. ==Personal life==
