Minister in the Prime Minister's Department Azalina Othman Said may have usurped the Dewan Rakyat speaker's power in issuing a blanket ban on questions pertaining to the RM2.6 billion donation scandal, as such a decision is not within her purview, argued opposition MPs.

"She's not the chair, it's not for her to decide. Azalina has overextended her powers as minister in charge of parliamentary affairs," Puchong MP Gobind Singh Deo said during a press conference at the parliament lobby today.

Gobind said the Standing Orders make it clear that only the speaker can make such a decision.

Asked if Azalina was usurping the speaker's powers in doing so, the DAP lawmaker said: "It seems so."
