Former prime minister Dr Mahathir Mohamad today published two letters, said to be from his then deputy Musa Hitam, to rebut Musa's claim that he resigned from cabinet after Mahathir accused Musa of trying to oust him.

Musa said this in his recently published memoir 'Frankly Speaking'.

Instead, Mahathir said on his blog, Musa resigned because he did not like Mahathir offering Gua Musang MP Tengku Razaleigh Hamzah the trade and industry minister post in 1984.

"To see how truthful Musa's frank story about himself, please read his two letters. The copy of the original is not legible, so I have printed the contents. You can compare," Mahathir said.
