Mexico's old rulers claim presidential election win

The party that ruled Mexico for much of the 20th century claimed victory in a presidential election on Sunday as exit polls showed its candidate, Enrique Pena Nieto, with a clear lead and primed to restore it to power after 12 years in opposition.

Pena Nieto, 45, of the Institutional Revolutionary Party (PRI), led by between 5 and 11 percentage points in exit polls published by three of Mexico's main television networks. (Reuters)
