The recently-opened Shimmy Club has installed the spyglass – normally associated with police interrogations – in two of its £800-a-time private function rooms.

A spokesman for the Glasgow venue, owned by millionaire entrepreneur Stefan King’s G1 Group, insists it does not allow male or mixed-sex groups to hire the rooms.

However, the Scottish Sunday Express has seen photos showing a group of young men with a clear view of women using the bathroom.

There is no sign in the toilets or anywhere else on the premises alerting female clubgoers to the fact they can be observed.
