Not really. It's every man for himself in UK jails.
There's not a gang problem in the UK in the way there is in the US. Yeah sure, you have your 'groups' of kids that grew up on the same estates that call themselves gangs, but it's nothing like the scale of gangs in other countries. They'll be about 50 strong max.
The worst 'gang cuture' you're likely to experience in the UK is the Yardies in Bristol and London. They control a lot of drug deals and sell guns throughout the UK, but they won't cause trouble unless they're fucked with.
Apart from small pockets of poverty, it's all rainbows and gumdrops over here
no now you have the post code gangs in nick...mostly young affenders ...right little cunts ..seen some nasty shit my self
