Indeed, such laws enjoy broad cross-party support.
A former adviser to President François Hollande, Mr Macron is now an unambiguous rival to his Socialist former mentor, whose own chances of running for re-election dwindle by the day.
France has a long history of trying to keep religion out of public life.
But the French are hyper-sensitive to signs of overt Muslim religiosity.Yet amid this feverish identity politics, some voices are trying to appeal for calm.Politicians, roused from their holiday hide-outs, seized on the burkini rowand not just on the right.This is a daunting challenge, not least because Mr Macron has never stood for election for any office before, is short of money and has little parliamentary support.It began with two terrorist attacks in Nice and Normandy, followed by a weeks-long political fixation with the burkini, a cross between a burqa and a swimsuit, which dozens of mayors of seaside resorts tried to ban from their beaches.This week France came back from the beach for la rentrée, the return to school and work after the August holiday.Mr Macrons departure had been widely expected.The row over the burkini will probably abate as the beaches empty.In lotto duży lotek wyniki losowania April he launched a new political movement, En Marche!The ex-minister is trying to build a platform of economic reform to resist populist nationalism.So does Marine Le Pen, leader of the far-right National Front, who claims that the soul of France is at stake.One is Alain Juppé, a centre-right former prime minister and presidential hopeful.The implication seemed to be that women in burkinis are un-French, while true French women go topless.It also seems to cut against the national mood.Freed from the constraints of the economics portfolio, Mr Macron will now be able to speak out on matters such as terrorism and religion.

On leaving his ministry, Mr Macron said that his government experience had taught him the limits of the current political system.He noted that Marianne, a female figure symbolising the French nation, is classically depicted bare-breasted.He now hopes to redraw the partisan map, pulling in support from both left and right for a pro-European, centrist movement that embraces globally-minded progressive politics.A law of 1905 entrenched the principle of laïcité, or strict secularism, after a struggle against authoritarian Catholicism.He backed the local burkini bans, but says national legislation would be provocative.
Nicolas Sarkozy, a former president vying for the nomination of the conservative Republican party, says he wants to ban the burkini altogether.
Hardline Islamists, he says, would not allow women to bathe in the first place.
The court ruled that the mayor had not proved any risk to public order, and that the ban constituted a manifestly illegal infringement of fundamental liberties.
