In an order that took more than five hours on foot to walk four kilometers to reach the famous Zocalo Square and in a precedent that is the first in decades, Mexican President Andres Manuel Lopez Obrador led a human wave of supporters of his policy on the streets of Mexico, amid a large crowd of his supporters

His spokesman said that more than a million people took part in this demonstration, which comes in preparation for the 2024 elections.

This is the first time that a Mexican president in office has led a demonstration since the days of Lazaro Cardenas (1934-1940), according to the website of the Spanish newspaper El Pais, citing historians, political scientists and academics.

At the end of the rally, the president presented the results of his four years in power in front of tens of thousands of people in the Zocalo chanting to him "you are not alone!".

But the president told the demonstrators "no to re-election" and seemed to dispel any hope they had that he would hold on to power. The Constitution provides for only one presidential term of six years.

For an hour the president presented his policy, which he presented as a break with more than 30 years of "neoliberalism", said "priority for the poor","to increase the minimum wage" and for budget austerity without creating "new debts".

Among other things, the Mexican president asked the United States to stop any hostile policy towards Mexicans working legally on the other side of the border.

Amid chants of "it's a great honor to be with Obrador," the president joined flag-waving crowds to personally lead a March that comes as his allies prepare for the 2024 presidential elections.

Lopez Obrador told reporters before the rally that the goal was to celebrate the "transformation" that the government has brought to Mexico four years after the start of his six-year term.

A banner at the rally read "the president is not alone," while others vowed to support the government's controversial electoral reform plan.

The march comes two weeks after tens of thousands of people took part in an opposition demonstration against Lopez Obrador's proposal to introduce changes to the country's most important electoral institution.

Lopez Obrador has an approval rating of almost 60 percent, and owes much of his popularity to social welfare programs aimed at helping the elderly and disadvantaged.

Presidents in Mexico are prohibited from staying more than one term in power. Lopez Obrador has ruled out the possibility of amending the Constitution to remain in office, but he wants his party "Morena" to remain in power after the end of his term.

Two close allies of Lopez Obrador who are considered the frontrunners to succeed him took part in the march: Mexico City mayor Claudia Sheinbaum and foreign minister Marcelo Ebrard.
