A native of
Bonneville, Haute-Savoie, Chikirou grew up in
Scionzier. She joined the
Socialist Party in 1997. From 2002 to 2007, Chikirou worked as a parliamentary assistant for Michel Charzat, who represented the
21st constituency of
Paris in the National Assembly. She was excluded from the party in 2006 along with Charzat after they refused to rally behind
George Pau-Langevin, the party's nominee for
2007 legislative election in the constituency. Charzat ran for reelection as a Socialist dissident under the
miscellaneous left label with Chikirou as his
substitute but was defeated. As a member of
La France Insoumise since 2016, she was
Jean-Luc Mélenchon's presidential campaign communications director in the
2017 election. In the
2022 legislative election, she was elected to Parliament for the
6th constituency of
Paris, where she succeeded one-term incumbent
Pierre Person of
La République En Marche! who declined to run for reelection. Sophia Chikirou has been a close associate of
Jean-Luc Mélenchon since 2011, serving as his press officer and later as his communications director during the 2012 and 2017 presidential campaigns. She founded the communications agency Mediascop, which managed Mélenchon's media strategy, introducing innovative techniques such as hologram appearances during rallies. Chikirou's influence extended beyond campaign periods, as she remained a key figure in shaping Mélenchon's public image and communication strategies. The 2025 investigative book
La Meute by Charlotte Belaïch and Olivier Pérou examines the internal dynamics of La France Insoumise, highlighting Chikirou's significant influence within the movement. The authors suggest that both Mélenchon and Chikirou contributed to an authoritarian atmosphere, drawing parallels to sect-like behaviour.
Manuel Bompard described the book as "a collage of gossip and false information". ==References==
