The luxury-loving wife of Malaysia’s former prime minister Najib Razak faced fresh questioning Wednesday by anti-corruption investigators probing a multi-billion-dollar scandal that contributed to the old regime losing power.

Rosmah Mansor, arrived at the offices of the Malaysian Anti-Corruption Commission (MACC) to be grilled. Local media reported this week that anti-corruption officials were wrapping up their probe into Rosmah, and she could be charged soon.

It was the second time she has been quizzed by the graft-fighting body since her husband’s coalition was unexpectedly booted out of office at elections in May after six decades in power.
