GUATEMALA CITY (AP) — President Otto Perez Molina has resigned amid a corruption scandal after Congress after a judge issued an order to detain him in the case.

Here's what to look for as the case moves forward.

WHAT ARE THE ALLEGATIONS AGAINST PEREZ MOLINA?

Prosecutor Thelma Aldana had said the president is suspected of illicit association, fraud and receiving bribe money in connection with a conspiracy that is believed to have bilked the government out of millions of dollars. Officials allegedly took bribes in exchange for letting businesses evade import duties through the customs agency. Former Vice President Roxana Baldetti is already in jail awaiting trial on similar accusations. Both deny any wrongdoing.

WHO BECOMES PRESIDENT NOW?

Vice President Alejandro Maldonado is constitutionally in line to assume the presidency. Maldonado, a conservative lawyer and former Constitutional Court judge, became vice president this year when Congress picked him from a shortlist of Perez Molina nominees. He replaced Baldetti, who resigned May 8 because of the corruption scandal. Maldonado would presumably remain in office until the winner of upcoming elections is inaugurated Jan. 14, 2016.

HOW WILL THE LEGAL CASE AGAINST PEREZ MOLINA PROCEED?

Timetables for criminal prosecutions are spelled out by Guatemalan law. For example, after Perez Molina appears before a judge following his detention order, prosecutors have three months to present evidence for a judge to order a trial. However there are often significant delays due to legal maneuvers, and it usually takes about a year to bring a suspect to trial. That could differ for Perez Molina depending on whether his case is linked to that of other suspects in the corruption probe. The courts could also freeze his assets, as has happened with Baldetti.

WHAT DOES IT ALL MEAN FOR SUNDAY'S ELECTION?

Not much, apparently. Political analyst Oscar Pelaez Almengor says the legal process against Perez Molina has "no effect" on the vote because elections are mandated by the constitution and overseen by the Supreme Electoral Court, not the presidency. So it looks highly unlikely that protesters' demands to postpone the vote will be met. However widespread anger over corruption and dissatisfaction with the current candidates could lead many to abstain or cast spoiler votes, undermining the eventual winner's mandate.
