[7] Following the announcement of the election date on 28 February 2024, clashes broke out in the capital N'Djamena after the government said that supporters of the opposition Socialist Party without Borders (PSF) attacked the headquarters of the National State Security Agency (ANSE), and attempted to assassinate the head of the Supreme Court, Samir Adam Annour.

[10] The attacks were condemned by the African Union, while French Minister for Europe and Foreign Affairs Jean-Yves Le Drian called for an impartial investigation into the incident.

[22] In a poll of 1,000 people residing in the 10 districts of N'Djamena conducted by the Center for Development Studies and the Prevention of Extremism, 487 of the respondents (50.94%) said they did not believe in the credibility of Chad's electoral authorities (the National Election Management Agency [fr] (ANGE) and the Constitutional Council) because they are under the control of supporters of Mahamat Déby.

[30] As part of his campaign, Succès Masra unveiled what he called a "minimum package of dignity", which includes a five-year plan to generate 200,000 jobs, divided equally between the private and public sectors.

[30] Following the election, Succès Masra and his Les Transformateurs party said that he and his supporters had been subjected to threats, violence and arbitrary arrests, adding that has his residence had been placed under surveillance.

Masra also accused the National Elections Management Agency of rigging the vote in favor of Mahamat Déby and urged voters to defend what he called their will expressed at the ballot box against massive electoral fraud.

[35] On 9 May, just before the release of provisional results, Masra claimed victory in a live broadcast on Facebook, calling on his supporters and security forces to oppose what he saw as an attempt to steal the election.

Provisional results were released later that day, indicating a decisive victory for Déby, who garnered 61.3% of the vote, surpassing the required threshold of 50% to avoid a runoff.

[41] On 12 May Masra formally appealed to the Constitutional Council to have the election annulled, saying that Les Transformateurs had amassed evidence of electoral fraud.
