By Nelson Renteria and Michael O'Boyle SAN SALVADOR (Reuters) - A former Marxist guerrilla leader is expected to win El Salvador's presidency on Sunday after promising to expand social programs for the poor and fending off his opponent's claims that he will impose radical policies. Recent polls showed Salvador Sanchez Ceren of the leftist Farabundo Marti National Liberation Front (FMLN), the rebel group in the country's 1980-92 civil war, with about 55 percent support heading into the second round run-off vote on Sunday. One of the wartime leaders of the FMLN, Sanchez Ceren faces conservative rival Norman Quijano, the former mayor of the capital, San Salvador, who trailed in polls with about 45 percent support as voting got under way. A Sanchez Ceren win would give the FMLN a second consecutive term and the affable, media-shy 69-year-old has vowed to build on its social programs, which include a glass of milk a day for children and free school uniforms, shoes and supplies.

International police agency Interpol confirmed that at least two passports recorded in its database as lost or stolen were used by passengers on the flight, raising suspicions of foul play. An Interpol spokeswoman said a check of all documents used to board the plane had revealed more "suspect passports" that were being further investigated. Malaysia's air force chief said the Beijing-bound airliner may have turned back from its scheduled route before it vanished from radar screens.
