Raja Petra Kamarudin

Raja Petra bin Raja Kamarudin (born 27 September 1950) is a Malaysian editor known for running the Malaysia Today website and publishing a series of commentary articles on Malaysian politics in the website. He is sometimes referred to by the initials RPK. He is currently residing in Manchester, England.

He was detained for a second time under the Internal Security Act, at 1.10pm on 12 September 2008. On 7 November 2008, Raja, 58, was freed from detention after Shah Alam city High Court Justice Syed Ahmad Helmy Syed Ahmad granted his habeas corpus petition and ruled that his detention was illegal. The court noted that "the grounds for the detention order by Home Minister Datuk Seri Syed Hamid Albar for the blogger did not fall under the scope of Section 8(1) of the ISA."

In May 2010 Cheras Umno Division chairman Datuk Syed Ali Alhabshee called on the government to strip Raja Petra of his citizenship on the grounds that his activities could affect the peace of the country.
