Mexico City’s military and police are out in force in preparation for this weekend’s Independence Celebrations

Stalls and celebrations in Mexico City’s Zocalo. The country is preparing to celebrate its Independence Day. This will be the first Independence Day to be presided over by the country’s current president Felipe Calderon, who took office in December last year following controversial elections.

Metal barriers and fences sprung up in the Zocalo almost overnight, according to bystanders. The military presence in the square is apparently much heavier than past years.

This banner was erected by supporters of Andres Manuel Lopez Obrador, Calderon’s left-wing rival in the controversial elections of last year. Calderon won the election by less than one percentage point, and opposition supporters still maintain that fraud plagued the election and that Obredor is Mexico’s legitimate president. According to the BBC, Mr Obrador, a populist former mayor of Mexico City, challenged the poll outcome in the courts and led a campaign of street protests. He refused to recognise Mr Calderon’s win.

Police guard the entrance to the Zocalo’s Palacio Nacional. Bystanders said that the heightened security of this year’s Independence Day celebration signals the Government’s fear that opposition supporters of Obredor could cause disruption over the weekend’s celebrations.
