An election for mayor of the city of Los Angeles has failed to produce a winner, but the two top finishers will face each other in a run-off in May.

None of the 12 candidates for the mayor's job won a majority in Tuesday's vote, but the incumbent and a Hispanic councilman emerged as the top finishers after the third place candidate, former California State Assembly speaker Bob Hertzberg dropped out.

City councilman Antonio Villaraigosa will face incumbent Mayor James Hahn in a May 17 vote. The two also competed against each other for mayor in 2001.

Los Angeles is the United States' second-largest city and one of its most diverse, with large numbers of white, black, Asian and Hispanic residents.

Mr. Villaraigosa is trying to become the city's first Hispanic mayor since 1872.
