The french prime minister weighs in:
The rules of public swimming pools must be respected and "no religious belief" can be taken into account to derogate from them, said Prime Minister Édouard Philippe after a punching operation carried out by burkini swimmers in a pool in Grenoble. "We know that if we don't respect this rule, things can quickly get out of hand. So enforcing it, strictly enforcing it is a republican imperative on which, I believe, we must not bargain," said the head of government during a live Facebook broadcast during which he answered questions from Internet users.
In public swimming pools, "there are rules about which outfits are the ones that must be used to come and swim. And no religious belief can stand in the way of respect for these rules, we must be firm with our rules," he insisted.
This firmness must prevail "not at all because it would be against this or that religion or against religion in general", but because the law "must guarantee strict neutrality. This is our conception of the Republic, this is the way we have chosen to live in our country," he said.
