JAKARTA (AFP) - Indonesia's powerful anti-corruption court sentenced a lawmaker to four-and-a-half-year in jail Wednesday, the latest in a string of heads to roll in the country's anti-graft drive. Sarjan Taher, a lawmaker from President Susilo Bambang Yudhoyono's Democratic Party, was jailed for receiving hundreds of thousands of dollars in bribes in return for allowing forest clearing on Sumatra island. Taher was paid $445,000 in bribes by authorities in South Sumatra province and distributed the money to fellow lawmakers, chief judge Gusrizal told the court. Another lawmaker was handed an eight-year jail sentence in connection with the case earlier this month, while one other is still on trial. Yudhoyono promised to stamp out corruption when he was elected in 2004 and while Indonesia remains one of the most corrupt countries in the world, clean government is shaping as a key issue for presidential polls in July.
