PKR treasurer-general and Wangsa Maju MP Tan Yee Kew has signed an online petition calling for the resignation of Latheefa Koya as the MACC chief.<br /><br />Speaking to Malaysiakini, Tan also urged others in Harapan, as well as its supporters to sign the petition and make their stand clear.<br /><br />"This has nothing to do with Latheefa's integrity and capability. She had been with us (PKR) for two decades to push for institutional reform.<br /><br />"But her appointment itself contradicted the institutional reform that we pushed for," Tan said, adding that Latheefa herself had betrayed the struggle for which she had fought so hard.
