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
