Mexico City ? Mexico’s top electoral court announced Monday that a partial recount of the votes in this country’s disputed presidential election found no evidence of widespread fraud, a ruling that placed conservative Felipe Calderon tantalizingly close to victory.

In a 7-0 ruling, the Federal Electoral Tribunal said it had found only minor mathematical and administrative errors in the initial vote count of the July 2 election. The tribunal said Monday its recount subtracted just 4,183 votes from Calderon’s margin of victory, reducing it to about 240,000 over leftist candidate Andres Manuel Lopez Obrador.

The panel still could refuse to certify the election, in part based on Lopez Obrador’s contention that President Vicente Fox and business groups illegally aided Calderon’s campaign. Such a decision appeared unlikely, political observers said.
