PARIS —  Nicolas Sarkozy launched a bid on Monday to win back the French presidency, announcing he would seek his party’s nomination to run in next year’s election.

The pugnacious 61-year-old conservative, who in 2012 ended a five-year term mired in unpopularity, had made no secret of his ambition to reconquer the top office.

"I have decided to be a candidate in the 2017 presidential election," Sarkozy wrote in a new book, Tout pour la France (All for France), due out this week.

"France demands that you give her your all. I feel I have the strength to lead the fight at such a turbulent moment in our history," he wrote in an extract seen by AFP, alluding to the terror attacks that have rocked the country since January 2015.

"The next five years will be filled with danger but also with hope." Sarkozy’s aides said he would step down as the leader of the centre-right Republicans to focus on his bid.

Laurent Wauquiez, from the party’s right wing, is expected to take the helm.

Party primaries take place on November 20 and 27. Sarkozy’s first campaign stop will be on Thursday at Chateaurenard, near the southern French city of Avignon.

Sarkozy itemised major challenges in the years ahead, including strengthening respect for "French identity," restoring lost competitiveness and enforcing state authority.

On the economic front, he vowed to reduce payroll charges, scale back unemployment payments for those who are jobless for more than one year and slash income tax by 10 per cent.

On immigration - a hot-button issue - he proposed "suspending" the right of family members to join a migrating relative in France. "The big problem with our immigration policy is firstly that of numbers," he said.

“Minority blackmail”

His announcement coincides with a resurgent debate on the place of Islam in French society, encapsulated in the row over the Islamic "burkini" swimsuit.

Sarkozy said France’s "principal battle" was over how "to defend our lifestyle without being tempted to cut ourselves off from the rest of the world".

The opposition leader, who has repeatedly dismissed Socialist President Francois Hollande as weak, said he would also restore authority in neighbourhoods where he said "minorities are successfully blackmailing the current authorities".

The politician was defeated in his bid for re-election in 2012 after conducting a campaign seen by many in his own camp as too rightwing. Sarkozy becomes the 13th person to put their name forward for the French presidency, a job that has sweeping powers.

He faces several challengers within conservative ranks. His chief rival, former premier and Bordeaux mayor Alain Juppe, who is seen as a moderate, is the favourite to win the party’s nod.

But Juppe’s lead in opinion polls has shrunk in recent weeks as Sarkozy steps up his rhetoric on Islamist extremists and immigration following the July 14 truck massacre in Nice. — AFP
