Mahathir was the CEO and Chairman, and hence a senior adviser, for many flagship Malaysian companies such as Proton, Perdana Leadership Foundation and Malaysia's government-owned oil and gas company Petronas. Mahathir and Abdullah had a major fallout over Proton in 2005. Proton's chief executive, a Mahathir ally, had been sacked by the company's board. With Abdullah's blessing, Proton then sold one of its prise assets, the motorcycle company MV Agusta, which was bought on Mahathir's advice. Mahathir also criticised the awarding of import permits for foreign cars, which he claimed were causing Proton's domestic sales to suffer, and attacked Abdullah for cancelling the construction of a second causeway between Malaysia and Singapore. Mahathir complained that his views were not getting sufficient airing by the Malaysian press, the freedom of which he had curtailed while prime minister: he had been named one of the "Ten Worst Enemies of the Press" by the Committee to Protect Journalists for his restrictions on newspapers and occasional imprisonment of journalists. He turned to the blogosphere in response, writing a column for "Malaysiakini", an online media news website, and starting his own blog. He unsuccessfully sought election from his local party division to be a delegate to UMNO's general assembly in 2006, where he planned to initiate a revolt against Abdullah's leadership of the party. After the 2008 election, in which UMNO lost its two-thirds majority in Parliament, Mahathir resigned from the party. Abdullah was replaced by his deputy, Najib Razak, in 2009, a move that prompted Mahathir to rejoin the party.
