PETALING JAYA (THE STAR/ASIA NEWS NETWORK) - Malaysian banker Datuk Seri Nazir Razak has posted a photo of Prime Minister Datuk Seri Najib Razak and his ex-deputy Tan Sri Muhyiddin Yassin on Instagram, calling it the duo's "last supper" together.

The picture was taken at a Raya Open House hosted by Nazir on July 27, one day before Muhyiddin was dropped from the Cabinet.

"One for the history books - Oblivious (host) to their last supper together," the CIMB group chairman posted from his account, nazir.razak, on Sunday.

In the picture, Najib and Muhyiddin were all smiles as they shared a light moment with Nazir, who is the younger brother of the Prime Minister.

Muhyiddin, who is Umno deputy president was dropped as deputy prime minister in a Cabinet reshuffle on Tuesday.

His ouster came just days after he made remarks on the troubled state investor 1Malaysia Development Berhad (1MDB). He said that he had asked Najib - who chairs 1MDB's advisory board - to step down from his 1MDB role but the Prime Minister had ignored his advice.

Muhyiddin had also been seen in a leaked video alleging that Najib had admitted to having US$700 million (S$962 million) in 1MDB funds deposited into his account.

Najib has in recent months faced heavy criticism from members of his party and the public for his handling of the allegations of abuse of public funds linked to 1MDB.

A Wall Street Journal report last month said that investigators in a 1MDB probe had traced US$700 million in funds deposited into bank accounts belonging to Najib.
