Recent police clashes with election-reform protesters in Malaysia have dented premier Najib Razak’s reform credentials and may force him to push back elections, analysts say. Najib was widely expected to set a June date for what is predicted to be a close battle between his ruling coalition and the opposition led by Anwar Ibrahim, but observers say Saturday’s protest may have changed his thinking. Tens of thousands took to the streets of the capital Kuala Lumpur to demand clean elections, defying government curbs on the rally. Angry demonstrators broke through barricades and clashed with police, who fired tear gas and chemical-laced water on crowds and arrested 512 people. All have since been released. Analysts say the events may have tarnished Najib’s efforts to win votes by pledging to loosen the long-ruling coalition’s authoritarianism.
