Former prime minister Najib Abdul Razak's daughter Nooryana Najwa has questioned why Anwar Ibrahim was allowed to campaign from jail for his wife during the Permatang Pauh by-election in 2015, but her imprisoned father has been prohibited from issuing any statement on GE15.

"Why could Anwar do so but not Najib?" she asked in a posting on Instagram yesterday.

She also uploaded screenshots of news excerpts on the matter, where one reported that Anwar’s message was conveyed, through his lawyer then, Latheefa Koya, for the people to vote for PKR and its candidate Dr Wan Azizah Wan Ismail.
