A key witness in Anwar Ibrahim's corruption trial, Ummi Hafilda Ali today urged Umno leaders to fully investigate all allegations against Puteri Umno pro-tem chief Azalina Othman Said in order to ensure that "justice" is given to the sacked deputy prime minister.

Ummi Hafilda, 35, who offered herself as the fifth candidate for Puteri Umno top post yesterday, said that the absence of investigation on Azalina would only reflect a double standard in Umno, and "would not do justice" to Anwar.

A controversial figure once dubbed as "Malaysia's Monica Lewinsky", Ummi played a major role in bringing down Anwar from a political star to a prisoner, where he is currently serving a 15- year jail sentence in Sungai Buloh prison.

"What is the difference between a woman who is alleged to be a lesbian and a man who is a alleged to be a homosexual, especially when the allegation came from the very same person?" questioned Ummi Hafilda, when contacted by malaysiakini .

Although she is satisfied that Anwar has been proven guilty, Ummi Hafilda said it is "unfair" for him to be in prison while another Umno leader, also accused of immoral activities, is allowed to go about freely without having to defend herself.

"While Anwar has the guts to defend himself, I am very disappointed that Azalina failed to do the same but simply hide behind top Umno leaders," stressed Ummi Hafilda.
