Voters queue up to cast their ballots during the general elections outside a polling station in Pekan, 300 km (186 miles) east of Kuala Lumpur May 5, 2013. Malaysians vote on Sunday in an election that could weaken or even end the rule of one of the world's longest-lived coalitions, which faces a stiff challenge from an opposition pledging to clean up politics and end race-based policies.
