No one in the country can be above the law or be exempted from being investigated, including Prime Minister Najib Abdul Razak's wife, Rosmah Mansor, Umno Youth chief Khairy Jamaluddin says.

"Nobody is exempted from being investigated. The law must apply to everybody," Khairy said.

He said this after being asked to comment on a startling allegation yesterday that RM2 million had been deposited into a bank account in Rosmah's name.
