I think it is missing the point to complain that M&S is encouraging the suppression of women by selling these garments.
It's like saying they are encouraging excessive alcohol consumption by selling fine wines.
No one has to buy a burkini and no one has to wear one.
Everyone seems to be assuming that Muslim women are forced to wear a headscarf, whereas my understanding is that the majority of them choose to, to demonstrate their adherence to their religion, which, let us not forget, is not that of the terrorists and the extremists.
As for the burkini itself, it strikes me as a very practical garment.
Here in the north-east, a group of nutters people brave the icy waters of the North Sea every day of the year.
If I were tempted to join them, the burkini would be my garment of choice
