BRITISH election observers in Mexico have praised the “professionalism” and “efficiency” of electoral staff during Sunday’s vote, which saw leftwinger Andres Manuel Lopez Obrador win the presidency by a landslide.

There were some reports of possible irregularities on the day itself, though they were relatively few in number, they told a press conference organised by Mexico’s Scholar and Citizen Network for Democracy (RUCD).

The elections were the bloodiest in Mexican history, with more than 130 candidates and party workers killed during the campaign and journalists targeted.
