Produced by Meicro for BBC Radio Cymru, Y Podlediad Trosedd is the station's first true crime podcast series. Presented by former Crown Court judge Nic Parry, the series revisits some of Wales' most significant criminal cases, combining legal analysis, archive material and first-hand accounts from journalists, police officers and key contributors.

The series explores stories including the murder of Julie Clarke, the wrongful conviction of the Darvell brothers, the Ysgol Dyffryn Aman stabbing and the Nathan Gill fraud and bribery case, examining not only the crimes themselves but their lasting impact on victims, communities and the Welsh justice system.
