سعود بن عبد العزيز آل سعود
On 10 September 2018, Najib posted a copy of the letter that purportedly came from Prince Saud Abdulaziz Al-Saud of Saudi Arabia on his Facebook account, as a proof of the alleged financial donation of US$100mil (RM304.5mil) given to him in 2011. He said he decided to reveal the documents in a bid to clear his name of various accusations and slander, and will continue to do so on his social media accounts.
