Mark Williams-Thomas


A multi award winning investigative reporter, Mark has amongst his awards, two Royal Television Society Awards, a Broadcasting Press Guild Award and an International Peabody Award. He is also BAFTA nominated.

A former police detective who has far-reaching experience of working at the centre of high profile investigations and undertaking major reviews Mark has, over the last decade, reported on nearly all the biggest crime stories including: The Alps murders, Tia Sharp murder, Claudia Lawrence murder and the murder of Alice Gross. One of Mark’s greatest skills is his ability to get exclusive access and interviews with key people related to the cases.


It was Mark’s programme in 2013 for ITV’s Exposure that finally exposed Jimmy Savile as one of the nation’s worst ever paedophiles. As a direct result of Mark’s investigation, the Metropolitan police set up Operation Yewtree, which led to the arrest of high profile celebrities Rolf Harris and Max Clifford.


In 2015, Mark beat the world’s media to gain exclusive access to Oscar Pistorius and his programme, Oscar Pistorius: The Interview, was broadcast on ITV 24th June 2016; the show has subsequently been broadcast around the world.


In 2016 after a yearlong investigation, Mark was given his own prime time ITV crime show: The Investigator. His first series reviewed the murder of Carole Packman who went missing in 1985: whilst her husband is in jail for her murder, her body has never been found. As a direct result of this series and the new evidence Mark found, Dorset police have now reopened the case.


In February 2016, Mark was given his own crime strand on ITV’s This Morning entitled Unsolved, which looked at undetected crime. His first three cases were the murders of Jill Dando and Claudia Lawrence and the disappearance of the Malaysian flight MH370.


Mark is currently working on a number of new programmes including series two of The Investigator.
