Mexican opposition wins key state election

Mexico's main opposition party has swept to victory in a crucial state election, strengthening its bid to retake the presidency and handing a major defeat to the governing conservatives.

Initial results on Sunday suggested that the PRI also strengthened its grip on two other states, brightening the political prospects for its PRI's main presidential hopeful, Enrique Pena Nieto.
