Life at Parc Prison, Bridgend, Wales' biggest jail

Privately-run Parc prison in Bridgend is the biggest jail in Wales and will soon be the biggest in the UK.

It has been commended by inspectors at a time when the UK government is weighing up the options for a super-prison in north Wales.

Parc is run by the security firm G4S, a company who faced stiff criticism recently over government contracts.

Reporter Daniel Davies went behind the prison walls to meet staff and inmates.
