The veteran presenter quit the BBC One consumer series earlier this month, and it has now been revealed that Sophie Rayworth and Michelle Ackerley will step into her shoes.
BBC News anchor Sophie will continue to front the broadcaster's One O’Clock News alongside her new role.
She already has a history with the long-running programme, having fronted spin-off editions ‘Watchdog Daily’ and ‘Watchdog Test House’.
Former CBBC presenter Michelle has also reported for ‘Watchdog’ and the ‘Crimewatch Roadshow’.
The pair will join remaining team members Chris Hollins and Matt Allwright when the series returns next month.
Speaking about her new role, Sophie said: “Watchdog is the reason I got into television.
“After doing two weeks work experience on the programme when I was 16, I was determined to become a journalist. I’m delighted to have been asked to join Matt, Chris and Michelle for the new series. It feels like I’ve come full circle.”
Michelle added: “I’m passionate about uncovering & investigating new stories and excited to work with Matt, Chris and Sophie. I'm genuinely excited to be part of such a fantastic team."
Chris Hollins also said: “I’m really pleased Michelle and Sophie are joining the team. I’m sure they’ll find it as rewarding as we do standing up for our viewers by protecting their rights.”
Matt Allwright also added: “I’m excited about the new stories we’ve got for this series of ‘Rogue Traders’.”
