The Other Side of Jimmy Savile

Williams-Thomas began investigating the Jimmy Savile case in late 2011, after being informed that Savile was investigated by Surrey police amid the 2007 Jersey child abuse investigation. On 3 October 2012, Williams-Thomas presented the Exposure documentary The Other Side of Jimmy Savile on ITV, in which five women stated that they had been sexually abused by Savile as teenagers. By late October 2012, the scandal had resulted in inquiries or reviews at the BBC, within the National Health Service, the Crown Prosecution Service, and the Department of Health.^[17][18][19] The exposure of Savile as a paedophile led to extensive media coverage, including 41 days on the front pages.^[20] In June 2014, investigations into Savile's activities at 28 NHS hospitals, including Leeds General Infirmary and Broadmoor psychiatric hospital, concluded that he had sexually assaulted staff and patients aged between 5 and 75 over several decades.^[21] In response to the documentary, the Metropolitan police launched the Operation Yewtree police investigation, which led to the convictions of high-profile celebrities (including Rolf Harris, Max Clifford, and Gary Glitter).^[22]

Williams-Thomas presented the follow-up documentary The Jimmy Savile Investigation later that year.^[23][24] The Other Side of Jimmy Savile and Exposure: Banaz: An Honour Killing won the 2012 Peabody Award which was broadcast on 3 October 2012.^[25][2] In 2013, Williams-Thomas won two Royal Television Society awards and the London Press Awards Scoop of the Year for the film.^[26][27][28] In September 2013, MP Tim Loughton made a statement to Parliament in which he praised Williams-Thomas for his "modest but game-changing ITV documentary that exposed Jimmy Savile".^[29]

Later television work

Following the success of the Jimmy Savile documentary, Williams-Thomas presented two further Exposure documentaries; Exposure: Predators Abroad^[30] and Exposure: Inside the Diplomatic Bag.^[31] His undercover work in Cambodia led to the arrest in 2013 of a person suspected of offering underage girls for sex and the rescue of two girls, aged 13 and 14.^[32]

In 2014, Williams-Thomas covered the verdict of Oscar Pistorius and was the only British journalist to meet with Pistorius during his trial, writing an exclusive report for UK national newspaper Daily Mirror.^[33] On 24 June 2016, ITV broadcast Oscar Pistorius: The Interview^[34] in which the former Paralympian spoke in a world exclusive to Williams-Thomas, in his first television interview about the night he shot and killed his girlfriend, Reeva Steenkamp in 2013.^[35] It was broadcast in Pistorius's home country of South Africa immediately after the ITV programme finished.^[36] On 11 November 2014, This Morning broadcast an exclusive interview with Jo Westwood,^[37] the ex-wife of sex offender Max Clifford.

The series was broadcast over four consecutive weeks on ITV, from 14 July 2016.^[40] Dorset Police subsequently confirmed that the case remained open and that they would be examining new evidence presented by Williams-Thomas.^[41] Series 2 of Williams-Thomas's crime series The Investigator returned to ITV in April 2018 in a three-part series. Series 2 of The Investigator featured the case of murdered student Jessie Earl, who disappeared from Eastbourne in 1980, her remains being found in 1989.^[42] In November 2020, in response to a campaign^[43] led by Williams-Thomas into Earl's murder, the Solicitor-General, in a highly unusual move, gave permission to appeal the verdict for a fresh inquest. The Rt. Hon. Michael Ellis QC MP said: "I have concluded the initial investigation was insufficient and further lines of inquiry should have been pursued. It is in the interest of justice the application for a new inquest be heard by the High Court."

In 2019 Williams-Thomas started investigating for a new crime series on the unsolved murder of teenage mum Nicola Payne. Payne, aged 18, who was from Coventry and had a six-month-old son at the time, went missing on 14 December 1991. She was on her way to her parents' home. Her body has never been found.^[44]

In September 2020 following the arrest of Charles and Doris Clark on suspicion of the murder of their 23 years old son Steven,^[45] who disappeared in December 1992, Williams-Thomas was given exclusive access to follow the family for a TV documentary while they were under police investigation.^[46]

In April 2022, in an interview discussing the Netflix documentary Jimmy Savile: A British Horror Story, Williams-Thomas revealed concern about it, saying that the series might be harmful to Savile's victims due to his face being featured throughout, stating that, "I do worry as far as victims go, it's one of the things that strongly gets criticised now when the story's talked about, seeing his face - his picture on the front page. For those victims to see his face consistently over and over again, that is very traumatic for them."^[47] Williams-Thomas made similar remarks in October 2023 about the crime drama series The Reckoning, which recounted Savile's crimes, in particular in the portrayal of an incident based on Claire McAlpine, who committed suicide aged 15 and left behind a note making allegations against several disc jockeys. Thomas criticised the casting of the character's race from white to Asian.^[48] Williams-Thomas was criticised for his comments about the character's race.^[49]

In December 2023, Williams-Thomas released a YouTube documentary, The Interview: Baroness Mone and the PPE Scandal,^[50] purportedly to investigate the government's controversial "VIP Lane" at the start of the COVID-19 pandemic.^[51] The documentary was funded by PPE Medpro, and featured a series of interviews with Michelle Mone and Douglas Barrowman, both of whom face allegations of fraud and bribery and have received significant public backlash for their association with PPE Medpro.^[52] Two experts who appeared in the documentary said they were "duped" by Williams-Thomas into appearing in the documentary.^[53] Williams-Thomas defended the documentary, stating that, "we have been totally upfront about who funded the programme." A strapline stating that PPE Medpro fully funded the documentary is inserted into the documentary, around 1 hour and 11 minutes in.^[54]
