Hundreds of people have joined in another protest calling for the resignation of the Guatemalan President Jimmy Morales - this time over his alleged involvement in illegal electoral financing.
Crowds gathered at the National Palace of Culture in the capital Guatemala City to demand the lifting of Morales's immunity.
Earlier this week, supporters of Ivan Velasquez, the head of the International Commission Against Impunity in Guatemala, CICIG, held a rally outside the Presidential House, urging Morales to stand down.
There had been speculation that Morales wanted the chief of the U.N. backed anti-corruption body to be removed from office.
In a joint probe with the Guatemalan Attorney General, Thelma Aldana, Velasquez has been investigating allegations of graft involving the President's older brother Sammy Morales and Jose Manuel Morales, one the president's sons.
On Friday, Velasquez said there was evidence that Jimmy Morales had broken laws when he was the head of his political party and prosecutors had filed a motion to investigate the him.
"In order to advance the investigation, it's necessary to remove his immunity," Velasquez told reporters in Guatemala City.
24 hours earlier, he had unveiled a probe into all political parties over alleged wrongdoing related to financing for the 2015 election campaign.
In a statement, the president's office said, "The President of the Republic has been and is respectful of the law and due process, and thus is confident in the objectivity of justice."
In the latest demonstration, protesters held signs with slogans saying "Out clown, the circus belongs to you" and "From president to delinquent, we support Ivan and Thelma (Aldana)".
If the Supreme Court of Justice approves the immunity request, Congress must form a commission to investigate if there are any grounds to lift it next week, which would require a two-thirds vote in the legislative chamber.
