Jean-Louis Thiériot

Jean-Louis Thiériot (born 26 June 1969) is a French politician and essayist who has represented the 3rd constituency of the Seine-et-Marne department in the National Assembly since 2018.

A lawyer by occupation, he is a member of The Republicans (LR).

Thiériot was elected to the municipal council of Beauvoir, Seine-et-Marne in 1995.

He has been described as economically liberal; he has notably written a biography of Margaret Thatcher (2007), which won the Grand Prix de la biographie politique, as well as a book about French Resistance leader and later President Charles de Gaulle: De Gaulle, le dernier réformateur (2018).

Thiériot previously served as Mayor of Beauvoir (2008–2018) and President of the Departmental Council of Seine-et-Marne (2018), in which he has represented the canton of Nangis since 2015.

In the National Assembly, he sits on the National Defence and Armed Forces Committee.

A graduate of Sciences Po in Paris, Thiériot holds a post-graduate degree (diplôme d'études approfondies, DEA) in history and a post-graduate diploma (diplôme d'études supérieures spécialisées, DESS) in European business law.

He was elected to the mayorship following the 2008 municipal election.

A winner of the Prix Robert-Christophe de l'Association des écrivains combattants for his 2009 book on Claus von Stauffenberg, which illustrates his interest in Germany and German-speaking skills, he also wrote France-Allemagne, l'heure de vérité (2011) with Bernard de Montferrand, a former French Ambassador in Berlin (2007–2011).

As a member of the National Assembly, Thiériot sits as a member of the Franco-German Parliamentary Assembly.

Thiériot regularly compares the political systems on both sides of the Rhine in articles published by Le Figaro.

At the 2012 and 2017 legislative election, Thiériot was the substitute for Yves Jégo in the 3rd constituency of Seine-et-Marne.

He became a member of the National Assembly following Jégo's resignation from Parliament due to his retirement from politics.

Active on police, justice and army issues, he is vice chair of the National Defence and Armed Forces Committee (Commission de la défense nationale et des forces armées).

He is also vice chair of the Groupe de travail sur la base industrielle et technologique de défense (BITD) within the committee.

He chairs the friendship group with Lithuania, holding a vice chairmanship of the friendship groups with Austria, Czechia, Latvia and Denmark.

He is a member of the friendship group with Australia.

Ahead of the 2022 presidential election, he advised The Republicans nominee Valérie Pécresse on defence matters.

In 2015, he was elected to the Departmental Council of Seine-et-Marne in the canton of Nangis.

He was an auditor of the 29th national session "security and justice" (2017–2018, Promotion Colonel Arnaud Beltrame) of the (now former) Institut national des hautes études de la sécurité et de la justice (INHESJ) and of the 72nd session "defence policy" of the Institut des hautes études de défense nationale (IHEDN).

Ahead of The Republicans' 2022 convention, Thiériot endorsed Bruno Retailleau for the party leadership, which was eventually won by Éric Ciotti.

In late 2023, Thiériot led a call to the government by seventeen The Republicans members of the National Assembly to help pass an immigration bill as amended by the Senate.

The members expressed their concern that a watered-down version of the bill would fail to pass the National Assembly; it was indeed rejected prior to examination on 11 December 2023, a first of this political importance since 1998, according to Le Figaro.

The bill finally passed by both houses of Parliament on 19 December 2023 was "hardened" compared to the failed version, as Thiériot had suggested.

Among others, he published "L'efficacité de l'Allemagne contre le virus contredit l'argument du manque de moyens" amid the COVID-19 pandemic in 2020.
