SAN SALVADOR (Reuters) - The runner-up in El Salvador's presidential election asked the electoral tribunal on Tuesday to annul the tight contest and threatened to go to the Supreme Court if necessary.

Norman Quijano of the right-wing Nationalist Republican Alliance (Arena) trailed Salvador Sanchez Ceren of the ruling leftist Farabundo Marti National Liberation Front in Sunday's vote by 0.22 percentage points, or fewer than 7,000 votes.
