Brahmi was the founder and former leader of the People's Movement,[1] which, under his leadership, won two seats in the constituent election in 2011.

He graduated from his alma mater, the Higher Institute of Management at Tunis University with a master's degree in accounting in 1982.

[6] On 25 July 2013, Brahmi was fatally shot in Tunis outside his Ariana home in front of his wife and children by two men on a motorcycle.

"[10][11] The suspect in both murders was identified as Abū Muqātil at-Tūnusī, a Salafist being sought on suspicion of smuggling weapons from Libya.

[12] A state funeral was held for Brahmi[13] and tens of thousands of people attended the procession to the Jellaz Cemetery in Tunis.

On 19 September 2013, Tunisia's interior minister told lawmakers the CIA informed authorities Brahmi was a target and said there had been a "failure" in the security services' response.

[18] She later claimed that Nidaa Tounes and Ennahda had had a pact to share the positions of president and vice-president of the Assembly, saying "the two parties of the political right, the one liberal and the other religious, joined hands under the table".
