COLOMBO: Sri Lanka's ruling party cruised to victory on Friday in parliamentary elections but fell short of the two-thirds majority that would have allowed President Mahinda Rajapakse to amend the constitution. Rajapakse's United People's Freedom Alliance secured 117 seats in the 225-member assembly with another 45 seats left to be declared, results released by the Elections Commissioner showed. The main opposition United National Party won 46 seats. Rajapakse's main rival, former army chief Sarath Fonseka, contested Thursday's poll from behind bars but his party secured just five seats.
