Are court backlogs creating miscarriages of justice? When the UK locked down, so did its court system, adding to a backlog that’s left defendants, witnesses and victims facing long waits for trials. Helen Grady speaks to people inside the justice system to find out how it’s coped with the pandemic - from delays in making courts covid-secure to a lack of PPE and overcrowding in prisons. We hear stories from prisons under lockdown and talk to lawyers who fear delays are leading to abuses of the criminal justice system.Producer: Rob Cave
