Kerri Pegg, ex-governor of HMP Kirkham, is latest in series of convictions of corrupt staff amid Prison Service crisis

As the former prison governor Kerri Pegg begins a stretch behind bars, marking the spectacular fall from grace of a woman once seen as a “rising star” within the service, she becomes the latest in an increasing number of corrupt staff experiencing the other side of a jail cell.

On Friday, Pegg, 42, was given a nine-year jail sentence for misconduct in a public office, after she entered into an inappropriate relationship with one of her prisoners, a convicted drugs boss.
