Supporters of Mexican left-wing presidential candidate Andres Manuel Lopez Obrador sealed main streets in Mexico City on Monday with 47 camps to support his call for a vote-by-vote recount of the July 2 election.
The camps blocked the main avenues leading from the city's Bosque de Chapultepec park to its main square, the Zocalo, or Constitution Place.
Obrador, who alleged that the election result was caused by a massive fraud, spent Sunday night at a camp in the square.
According to the Federal Electoral Agency (IFE), the institution charged with counting the country's votes, Felipe Calderon of the right-wing National Action Party won just under 244,000 votes, a 0.58-point margin, over Obrador.
Obrador has challenged the result with the Federal Electoral Tribunal (TEPJF), a body of seven judges that ratifies the nation's election results. The tribunal must settle all electoral disputes by Aug. 31 and name a president-elect by Sept. 6.
Also on Monday, representatives of Mexico's business community called for the resignation of Mexico City Mayor Alejandro Encinas, who is from Obrador's Revolutionary Democratic Party, and has been accused of illegally supporting Obrador's political campaign.
The business people said they had lost millions because the protests prevented clients reaching their malls, banks and shops.
Authorities sealed streets on either side of Reforma Avenue to prevent traffic from building up in the streets near the camps. Reforma, where the country's stock exchange is located, is one of the city's busiest streets.
