It was announced in January 2023 that Colin Murray had moved from interim host to permanent host. Guest hosts would return later that year as part of the show's 40th anniversary celebrations, with Floella Benjamin, Richard Coles, Trevor McDonald (for a second time) and Moira Stuart each hosting one week's worth of episodes. On 25 July 2022, it was announced that Les Dennis would guest host the show from 4 to 15 August followed by Jenny Eclair from 16 to 19 August because Colin Murray tested positive for COVID-19. Colin Murray then returned on 14 July as a stand-in host. The programme was then presented by Anne Robinson (its first female presenter) from July 2021 until July 2022. It was then presented by Des Lynam from October 2005 until December 2006, Des O'Connor from January 2007 until December 2008, Jeff Stelling from January 2009 until December 2011 and Nick Hewer from January 2012 until July 2021, with Colin Murray standing in for Nick Hewer during part of the COVID-19 pandemic. The programme was presented by Richard Whiteley for 23 years until his death in June 2005.
