G4S has been fined at least 100 times for breaching its contracts to run prisons since 2010, according to data obtained by Labour.
Andrew Selous, the prisons minister, revealed that almost £3m has been paid in fines since David Cameron came to power, after Labour made repeated requests to the Ministry of Justice (MoJ).
The data showed that one prison alone, HMP Rye Hill, has been fined on 28 separate occasions and incurred £1m in penalties.
In total, eight institutions had to pay back £2.7m over 100 separate occasions, although Selous stressed that the department uses the term “financial remedies” rather than “fines”.
G4S management of prisons has been under particular scrutiny since an undercover BBC Panorama investigation exposed footage of staff appearing to use excessive force on children at the Medway secure training centre (STC) in Kent.
Louise Haigh, Sheffield Heeley MP and a shadow civil service minister, said Labour had to “prise this vital data out of the hands of a desperately reluctant MoJ”.
“This reveals that G4S are failing repeatedly on contracts worth billions of pounds with over 100 contractual failings in just five years,” she said. “With G4S responsible for the safety, security and smooth running of some of our most high-profile prisons this is a troubling revelation.
