Jeremy Vine has been announced as the new host of Crimewatch, alongside lesser known BBC broadcaster Tina Daheley.
The long-running series will return with Radio 2 host and former Strictly Come Dancing competitor Jeremy and Tina, who presents the news on Radio 1´s Breakfast show and weekend stints on Breakfast, this autumn.
Kirsty Young revealed in November that she was stepping down after seven years, saying it was a "privilege" to host the crime-solving show.
The show will go out weekly, with live broadcasts from a mobile incident studio near the scene of a key crime.
Staples of Crimewatch such as appeals, dramatic reconstructions, CCTV footage and "wanted faces" will continue in the new format.
Both presenters said they grew up watching the long-running programme.
Jeremy said: "It is one of the most powerful programmes the BBC has ever broadcast, with the power to change and save lives, and of course to solve crimes.
"To present it is a great honour and with this new format Crimewatch will be even more at the heart of the BBC One schedule."
Tina, currently in Ibiza for the Radio 1 breakfast show, said: "I feel very privileged to join a programme that's allowed ordinary viewers to help bring criminals to justice and make our communities safer.
"Young people often suffer most from crime, so I'm especially keen to use my journalistic skills and experience engaging young audiences at Radio 1 to make sure they feel part of the new-look show."
Viewers will be able to respond to appeals immediately using the Crimewatch phone line, as well as texts and email.
Audiences will be kept up to date with developments on the cases immediately after and in the week between each episode with postings online.
Crimewatch's executive editor Joe Mather said: "Jeremy is the ideal presenter to lead such an important and established BBC One series. He has the perfect mix of serious journalism alongside genuine empathy towards the victims of crime and their families.
"Tina is an incredibly strong broadcaster and journalist, delivering daily live news to the listeners of Radio 1 as well as sports and arts coverage across the BBC."
Previous presenter Kirsty joined Crimewatch in 2008. She worked on many high-profile appeals, including over the disappearance of Madeleine McCann and the Hatton Garden heist.
Following its September 2016 run, Crimewatch will return to BBC One for its next block of episodes in early 2017.
