Tengku Razaleigh Hamzah
Early during Mahathir's tenure as prime minister, a bitter dispute erupted within the ruling UMNO party and it was divided into two camps, which were colloquially known as 'Team A', comprising Mahathir loyalists, and 'Team B', which supported former Minister of Finance Tengku Razaleigh Hamzah and former Deputy Prime Minister Musa Hitam. Mahathir prevailed, leading to the exclusion of Tengku Razaleigh Hamzah from the newly established UMNO (Baru) or New UMNO. Abdullah was a close supporter of his political mentor Musa Hitam in Team B and as a result, he was sacked from his post of Minister of Defence in the Cabinet. He did not join the Semangat 46 (Spirit 46) party which was set up by Tengku Razaleigh Hamzah. Semangat 46 is now defunct.
