Nominated sub-prefect (sous-préfet hors-classe), he then worked alongside the prefect of the region Centre. Guéant then became general secretary of the prefecture of the Hérault department and then of the Hauts-de-Seine. In 1991, he was nominated prefect of the Hautes-Alpes department.
During the second cohabitation (Édouard Balladur's government), he was named deputy-director of Charles Pasqua's cabinet, who was at the time the Minister of Interior. In 1994, he was named general director of the national police.
He has been closely associated with Nicolas Sarkozy since at least 2002. From 2002 he was Sarkozy's chief of staff (directeur de cabinet), following him to the Ministry of Finance in 2004, then to the Ministry of the Interior from June 2005 to March 2007. During the 2007 presidential campaign, he was in charge of Sarkozy's campaign. and was named general secretary of the Elysée on 16 May 2007. He is particularly listened to by Sarkozy, and his power has given him many surnames such as the "Cardinal",[1] "Prime Minister bis", or "Vice President".[2]
On 27 February 2011, he was nominated Secretary of the Interior (Ministère de l'Intérieur). Though Alain Juppé has explicitly denied it,[3] many have claimed that Guéant's departure from the post of general secretary was a sine qua non for Juppé to accept the Minister of Foreign Affairs position the same day, due to Guéant's meddling in foreign policy since his appointment in 2007.[4][5]
In 2015, Guéant was given a two-year suspended prison sentence, barred from public office for five years, and fined €75,000 for taking €210,000 over two years from a cash fund intended for police investigations and using it to award bonuses to himself and his staff.[6] In 2019 a French court rejected his appeal, sentencing him to one year in prison.[7]
In October 2021, the Judicial Tribunal of Nanterre announced that Claude Guéant will be tried for "illicit financing" of his legislative campaign of 2012, because of the distribution of a leaflet in his favor by the mayor LR of Boulogne-Billancourt (Hauts-de -Seine). On 21 January 2022, Guéant and three co-defendants, writer and one-time Sarkozy advisor Patrick Buisson, former cabinet director Emmanuelle Mignon and former pollster and consultant Pierre Giacometti, were found guilty of polling fraud involving allegations that they misused public money while ordering public opinion polls worth a combined 7.5 million euros ($8.7 million) during the course of Sarkozy's presidency between 2007 and 2012 and was sentenced to eight months in jail.[9][10] He would be released on parole on 9 February after it was determined that he repaid the French treasury 292,000 euros in damages.[11][12]
