The prime minister's brother Nazir Razak has described 1Malaysia Development Berhad's (1MDB) failure to testify at the Public Accounts Committee (PAC) hearing scheduled for today as "unacceptable".
"Your company has triggered a national crisis and you can be too busy to face Parliament? Unacceptable," he said in a posting on Instagram.
He was referring to 1MDB president Arul Kanda and former chief executive officer Shahrol Halmi's abrupt request for a 30-day extension before testifying to the PAC, citing important overseas appointments.
The duo only made the request four days before the hearing despite receiving two-weeks notice from the PAC.
Nazir, who is CIMB chairperson, has been a critic of 1MDB over its massive debt which he said has affected investor confidence.
1MDB is wholly owned by the Finance Ministry, a portfolio held by Prime Minister Najib Abdul Razak, who first pushed for the creation for 1MDB and sits as chair on its advisory board.
Arul in a statement yesterday insisted that he and Shahrol will testify before the PAC eventually.
"As confirmed by the chairman of the PAC earlier today, the date for this appearance is currently being finalised, due to a date proposed earlier being in conflict with previously scheduled overseas commitments," he said.
In February, Nazir and his siblings also appeared to be at odds with Najib ( photo ) after the Prime Minister's Office (PMO) claimed Najib had received an "inheritance" from their father, former prime minister Abdul Razak Hussein.
The PMO was responding to queries by the New York Times to explain alleged stacks of cash at Najib's home and his family's alleged luxurious lifestyle.
This prompted Abdul Razak's children, with the exception of Najib, to issue a joint press statement, stressing that their father lived a frugal life and any suggestions otherwise tarnishes his memory.
Last month, Nazir said disagreements between siblings were " normal " when asked if he was at odds with Najib.
