For some inexplicable reason I felt the need to have a look at the Manchester Evening News tonight (the local paper for Manchester). On their webpage was a story concerning Levenshulme (an inner suburb in Manchester) and their public swimming baths. They report that over the past nine months the pool has been hired out on a Thursday evening for private naturist group Naked Swim. The group is for gay men and they use a private pool at the baths and make use of the sauna (again only they have access).
Local mothers have now found out about the group (despite them using it since last summer) and are concerned that their children are having swimming lessons in a pool that adults are naked (albeit at a completely different time). The parents claim their concerns are around hygiene but the pool management have dismissed that. You can read the story here.
