Sadiq Khan today condemned France's "burkini ban" as he travelled to Paris to discuss community integration with the city's mayor.
The Mayor waded into the row after pictures emerged of French armed police apparently fining a woman in a headscarf on a beach in Nice.
France's supreme court of appeal was today preparing to rule on the burkini ban in several cities and towns.
Mr Khan told the Standard: "I'm quite firm on this. I don't think anyone should tell women what they can and can't wear. Full stop. It's as simple as that.
