Rosmah Mansor, the wife of the former prime minister, is expected to be called in by the MACC again tomorrow.

A source close to Rosmah said her lawyer, Geethan Ram Vincent, received a call from the MACC at 6pm today, and that she would be appearing at the commission's Putrajaya headquarters at 11am.

The source said that this will likely be the last round of questioning, and feared that Rosmah may be detained tomorrow.

If Rosmah is indeed detained, she could be charged in court on Thursday – the same day her husband Najib Abdul Razak's criminal charges are up for case management at the Kuala Lumpur High Court.

Meanwhile, a high ranking MACC source confirmed with Malaysiakini that Rosmah would be called in tomorrow.

This will be the third time that the commission is questioning Rosmah. Her previous round of questioning lasted 13 hours. 

It was previously reported that she could face up to 20 charges.

Besides the MACC, the police are also looking to question Rosmah over jewellery items seized from residences linked to Najib.
