Presidency puzzle

THE battle for Mexico’s presidency has turned from a nasty campaign of mudslinging into a tense tug of war in court.

Apparent winner Felipe Calderon said late on Monday his conservative party had evidence showing that last week’s election was clean and discrediting legal challenges by leftist rival Andres Manuel Lopez Obrador.

Mr Lopez Obrador and his campaign staff claimed that a network of federal officials, prosecutors and possibly even judges collaborated in a broad conspiracy to steal last week’s elections.
