Many people have gathered in Mexico City to show they are against changes to the electoral authority before the presidential elections in June.
The Mexico City government said about 90,000 people came to Zocalo Square in the city. The rally organizers said there were many more people than originally thought.
The opposition says President Andrés Manuel López Obrador is trying to make the National Electoral Institute weaker. The Institute is a group that is independent and doesn’t support any political party.
He says the INE is unfair and dishonest.
Since he won the 2018 presidential elections, Mr. López Obrador has been trying to change the INE. He says it will save taxpayers $150m (£119m) a year by greatly reducing the agency’s workers.
The protest on Sunday in the old square of the capital is the most recent protest in Mexico in the last few years.
We want to protect our independent organizations and defend our democracy. We want the INE to be safe from attacks. “We want to make our own decisions, and we don’t want the president to interfere with the election,” said protester Diana Arnaiz according to AFP news agency.
Maria de Jesus Torres, who was also at the rally, said: “There are many Mexican people who do not like this government, and I am protesting for my kids and grandkids. ”
Mr López Obrador cannot run for president again because Mexican presidents can only serve for one six-year term.
He is helping former Mexico City Mayor Claudia Sheinbaum, who is currently ahead in the opinion polls.
Ms Sheinbaum, who is part of the Morena party, officially joined the race by handing in her registration papers on Sunday.
