There’s a saying amongst regular prison inhabitants that you can get put in any jail in the world and you’ll bump into a Manc and a Scouser.
People who’s dealings with scousers is limited to football rivalry might be surprised to hear that traditionally scousers and Mancs get on well together on the whole in jail. Football really isn’t that big a deal in jail.
This thing about Muslims running UK jails, I suspect is bullshit put out by the usual shit stirrers in the media and on socials. Yes, they normally stick together and maybe in somewhere like Belmarsh, where they stick all the terrorist suspects, it may be different, but in regular jails, not so much.
Virtually all trouble in jail is over drug debt. And nobody is too fussy what religion you are or where you come from, when it comes to dealing with that.
