The Malaysian Anti-Corruption Commission (MACC) has obtained an explanation from the source of the RM2.6 billion donation deposited into Prime Minister Najib Abdul Razak's personal bank accounts.

However, the commission said it cannot reveal the identity of the donor, whom it said was from the Middle East.

"MACC obtained details of the donor from bank documents and found there were four letters submitted to the bank when the large sum of money was deposited into the prime minister’s accounts.

"In the documents, it was stated that the RM2.6 billion was donation," read the statement.
