Political career
At the outset of his political career, Teissier was a member of the "extreme right-wing group” of the Nationalist Union. He then joined the New Forces Party, becoming a member of its Central Committee in 1976. In 1978, he joined the Republican Party, then switched to the Liberal Democracy Party, run by his friend Alain Madelin. In the latter party he served as Deputy Secretary General and was in charge of security and defense issues. Still later, he joined the Union for a Popular Movement, and sat on its nomination committee. In 2015, the UMP changed its name to the Republican Party.
Departmental council for Bouches-du-Rhône
In 1982, Teissier ran successfully against Jean-Victor Cordonnier for a seat on the departmental council. He was re-elected in 1985, 1992, and 1998. During that period, he was president of the opposition in the council. In March 2004, running again two other candidates, he was re-elected to the post of councilor general in the canton of Sainte-Marguerite with 46.7% of the votes; he resigned from this post in November of that year to devote himself fully to his other political responsibilities.
Mayor of a sector of Marseille
Since 1983, Teissier has been a member of the Marseille city council. He was elected mayor of the 5th sector in 1983, and re-elected to that chair in 1995, 2001, and 2008. In the municipal elections of March 2014, Guy Teissier once again was at the top of the list in the 9th and 10th arrondissements. In the second round of votes, Teissier's list won a three-way contest with more than 51.4% of the votes, while Jean-Claude Gaudin, his local party leader, was re-elected mayor of Marseille. After the election, Teissier gave his seat to one of his relatives, Lionel Royer-Perreaut.
Deputy from Bouches-du-Rhône
Teissier campaigned in 1988 to represent the 6th constituency of Bouches-du-Rhône. In the June elections he defeated businessman Bernard Tapie, but the election was nullified in November by the Constitutional Council. In 1993, he was again elected to represented the 6th constituency. During the ensuing period, he held the position of Secretary of National Defense and Armed Forces in the National Assembly. He went on to write several parliamentary information reports. He was re-elected in 1997 and became Secretary of the National Assembly, a post he held until 1999. He served on the Committee of Defense and the Armed Forces and on the Supreme Council of the Military Reserve. He was re-elected in 2002 with 76% of the votes cast, the highest percentage received in that year's election by any candidate for the National Assembly. His colleagues selected him to be president of the Committee of Defense and the Armed Forces. In this capacity, he chaired the Defense Procurement Control Mission of the Department of Defense, and wrote a new report on the Military Reserves. In 2003, he met with all the major figures in French and European defense under the auspices of the Summer Universities of Defense in Pau. Re-elected yet again in June 2007, with 55.30% of the votes in the first round, Teissier was reappointed to the presidency of the Defense Committee. In January 2008, he was appointed President of the Parliamentary Intelligence Delegation, responsible for oversight of all French intelligence services. In June 2012, he was re-elected with 42.45% of the vote in a three-way contest. He remained on the Foreign Affairs Committee, served as president of the Espace study group, and was a member of several others, in addition to serving as vice-president of the friendship groups with Armenia, Israel, and Latvia. He was re-elected again in June 2017.
Urban community of the Marseille Provence conurbation (MPM)
He was elected community councilor in 2001, and re-elected to this post in 2008 and 2014. On April 7, 2014, he was elected president of the MPM with 90 votes, out of a total of 137, succeeding Eugène Caselli in this post. Teissier promised to seek to revitalize MPM in the run-up to its 2016 expansion into the Aix-Marseille Provence conurbation, which includes 93 municipalities with a total of 1.8 million inhabitants. In 2008, Guy Teissier was elected Chairman of the Board of Directors of the Euro-Mediterranean Public Planning Institution, a large urban-renewal project in central Marseille.
