Since winning a landslide election victory on Jul 1, leftist Lopez Obrador has painted himself an everyman president, forgoing the traditional trappings of the presidency, but the absence of armed guards has raised fears in a country reeling from political, gang and drug-related violence.
There were more fatal attacks on politicians during the last election campaign than in any other in recent history, and an epidemic of gang violence made last year Mexico's deadliest since modern records began.
Giving his first public comments a day after being officially named president-elect, Lopez Obrador said ten men and ten women would be chosen to provide his security, but described them as facilitators. He said they would not carry firearms, and protection would be kept at a minimum.
"All Mexicans are going to take care of me, but there will not be this special (government) body to guarantee the protection of the president of the republic."
Lopez Obrador said he told current President Enrique Pena Nieto, who is protected by 2,000 armed presidential guards, composed of military personnel, police and civilians, that he would instead go with the much smaller security team.
Lopez Obrador has promised to run an austere, zero-deficit government, and his approach to security is a clear example of how he is breaking from the mold. The current presidential guards will be absorbed by the defense ministry once he takes office on Dec. 1.
He has promised to turn the presidential Los Pinos palace into a cultural centre, have the presidential plane sold and receive half the salary of Pena Nieto.
