MACC has summoned Rosmah Mansor to its headquarters in Putrajaya next Tuesday to facilitate investigations into the SRC International Sdn Bhd issue.
According to the notice, the wife of former premier Najib Abdul Razak must be present at 11am for her statement to be recorded.
Last week, MACC had quizzed Najib twice over the SRC International case.
In 2015, MACC had been pursuing a case related to SRC International over purported funds that flowed into Najib's personal bank accounts.
At the time, whistleblower website Sarawak Report had claimed that there were some well utilised credit cards linked to those personal accounts.
SRC International had secured two separate RM2 billion loans from Retire Fund Incorporated (Kwap) in 2011 when it was part of 1MDB and in 2012 after it was absorbed by the Finance Ministry.
This was spent on various investments abroad. The Najib-administration did not announce if any of these investments have borne fruit.
Malaysiakini had reported on Wednesday that SRC International was insolvent and that its assets could not produce the returns necessary to service the RM4 billion loan from Kwap.
Therefore, it was the Finance Ministry which has been making regular payments to Kwap.
