PETALING JAYA: As someone who has known Datuk Dr Xavier Jayakumar for a long time, PKR secretary-general Datuk Seri Saifuddin Nasution Ismail says the former’s decision to leave the party raises “many queries”. “What differentiates a true reformist from others is the strength in facing challenges in good and in trying times, ” he said. He said the Kuala Langat MP had informed party leaders about a recent investigation by the Malaysian Anti-Corruption Commission. On Feb 17, he had complained that his reputation as an elected representative was being sullied by media reports linking him to a party colleague who was being investigated for graft.
