Poniatowski took a founding part in the
Independent Republicans (RI) party, and became an RI
deputy for the
Val-d'Oise in 1967, as well as the general secretary of the Confederation of the Independents before taking the presidency of the party's successor, the
Republican Party, in 1975. He was elected mayor of
L'Isle-Adam (France) in 1971.
Bernard Lehideux served Poniatowski as of his office in 1969. Poniatowski was then named
Minister of Public Health and Social Security from 5 April 1973 to 27 May 1974, under the government of
Pierre Messmer.
Minister of the Interior and State Minister (1974–1977) Poniatowski succeeded
Jacques Chirac on 24 May 1974 and served in the post until 1977. Considered as the main organiser of
Valéry Giscard d'Estaing's victory at the
1974 presidential election, he was named
Minister of State and
Minister of the Interior on 27 May, which changed the official protocol of the Republic: the most important minister was no longer the
Minister of Justice. Although he was a strong-handed Interior Minister, he suppressed the personal registers (
fiches signalétiques), which customers of a hotel were to sign, a custom that remains in force in many countries. In August 1975, he sent the
French military to repress the nationalist rebellion in
Corsica by
Edmond Simeoni, who had illegally occupied a
wine cave in
Aleria. Two
gendarmes were killed during the assault, leading him, along with Chirac, of being accused of a large part of the responsibility in the violence that hit Corsica. Following the assassination of Prince
Jean de Broglie, a Giscardian deputy, ''
L'Express (January 1977) and then Le Canard enchaîné'', in 1980, published documents alleging that Poniatowski had known in advance of the death threats on de Broglie but not acted accordingly. The satirical newspaper recalled that de Broglie had been treasurer of the Independent Republicans and tied to the Matesa scandal, which allegedly funded the RI. Soon after the affair and the failure of the right wing at the March 1977 municipal elections, Poniatowski quit the Ministry of Interior and would not be called again as minister. After leaving the Barre government, Poniatowski served as the President’s special envoy with the rank of ambassador and, among other things, traveled to
Tehran on December 27, 1978, for a meeting with Shah
Mohammad Reza Pahlavi to assess the situation in Iran on behalf of the President in preparation for the
Guadeloupe Conference. In his report, Poniatowski described the Shah as “dignified and of sound mind, though tired, sad, and disillusioned. He felt abandoned by his friends and by the outside world.” The Shah had hoped that the United States would continue to support him. == 1980s ==
