"I will be the president that reestablishes the authority of the state," he said, saying he would protect the French and insisting it was not "fascist" to be concerned about security.
In a speech filled with conservative political red meat, Sarkozy also promised to institute compulsory military service for "dropouts" who were not employed or in fulltime education at the age of 18.
The speech was received with horror on the Left, with commentators on social media observing that Sarkozy sounded indistinguishable from Marine Le Pen, the National Front leader whom polls suggest could reach the second round runoff in the presidential election next year.
Sarkozy's speech came as the debate continued to rage in France over a ban on the burkini after armed police were photographed on a beach in Nice forcing a woman to remove her headscarf and other articles of clothing.
The images sparked an outcry on social media, which led Christian Estrosi, the Deputy Mayor of Nice, to threaten he would prosecute "those who spread photographs of our municipal police officers and those uttering threats against them on social networks".
Support for banning the all-covering swimsuits is not confined to the Right, however, with Manuel Valls, the French Prime Minister again yesterday reiterating his belief that the burkini was a "symbol of the enslavement of women" and must be banned. "We have to wage a determined fight against radical Islam, against these religious symbols which are filtering into public spaces," he said in a television interview.
