The Berlin authorities agreed that they had been victims of discrimination and changed their clothing rules, establishing equal rights for all Berliners, whether male, female, or non-binary.

The decision is expected to be welcomed by Germany's freikorperkultur, or free body culture.

Germany famously has a relaxed attitude to nudity, but the issue of whether and to what degree that is permissible at municipal swimming pools has plagued many local authorities.

The new rules apply to all visitors at Berlin's public pools and create legal certainty for staff.
