DHAKA (AFP) - Bangladesh's prime minister-elect Sheikh Hasina Wajed was sworn in as a member of parliament and elected the leader of the house Saturday after winning a landslide election victory last week. The Awami League (AL) party chief's election by three-quarters of the MPs completed the last formality before she is sworn in as premier by President Iajuddin Ahmed on Tuesday, party spokesman Abul Kalam Azad said. Members of opposition parties who make up the remaining seats in parliament were due to be sworn in on Sunday. Sheikh Hasina's AL party won 230 out of a possible 300 seats in Monday's polls. She has been leading the party since 1981 and this will be her second term as prime minister. She held the post after her party's narrow 1996 poll win over the Bangladesh Nationalist Party (BNP) of archrival Khaleda Zia. Her party earlier on Saturday brushed aside speculation that it would appoint a fresh face as prime minister. "Sheikh Hasina will be the next prime minister of the country. The party does not have any other alternative," party general secretary Abdul Jalil said. Held under tight security, the first polls since 2001 attracted a turnout of 87 percent and saw none of the deadly unrest that forced the last scheduled vote to be cancelled and saw the army-backed administration take control. After alleging election fraud in the immediate wake of the results, the BNP on Thursday accepted defeat, but stood by its charge of vote rigging. Independent observers, including a team from the European Union, have declared the election free and fair. The Awami League said it would appoint veteran party official and ex-minister Zillur Rahman to be Bangladesh's next president, once parliament is convened. The head of state has had little authority over day-to-day affairs since a change in the constitution in 1991 vested most powers in the prime minister.
