Malaysian opposition leader Anwar Ibrahim (C) speaks during a rally to protest Sunday's election results at a stadium in Kelana Jaya, outside Kuala Lumpur May 8, 2013. Anwar vowed on Tuesday to lead a "fierce movement" to reform the country's electoral system and challenge the results of an election he lost, starting with a rally of supporters this week. Anwar has contested the results of the most closely fought election since Malaysia was engulfed in race riots in 1969, accusing the ruling party of fraud, including the use of immigrants as proxy voters, charges the government denies.
