Inside the 'squalid' private jail taken over by violent, drug-taking inmates while guards hide in offices

With prisoners smoking drugs, listening to music and playing with their mobile phones, this is the inside of a jail where inmates "have more power than staff".



A clip taken inside HMP Birmingham this year shows one lag puffing on what appears to be a cannabis joint while others play pool.



Another seemingly shows a prisoner slumped down after seemingly taking the drug Spice behind bars.



The government has finally had enough of poor standards at the G4S-run jail, and has been forced to step in and take control.



Inspectors found the prison in “an appalling state” with high violence, widespread bullying, squalid living conditions and poor control by fearful staff.



In the video which emerged earlier this year, prisoners livestreamed themselves jokingly calling themselves the "slider gang" - due to their matching blue and white striped flip-flops.
