Jo Whiley is to co-present a new, extended drivetime show with Simon Mayo, as Radio 2 overhauls its schedule.
Whiley will be the first female DJ on the station’s weekday daytime schedule for 20 years.
Debbie Thrower was the last, presenting Radio 2’s afternoon show between 1995 and 1998.
Gary Davies replaces Cox on the popular Sound of the 80s programme while 6 Music’s Cerys Matthews takes over the Blues Show from Paul Jones, who leaves the station after more than 30 years.
The Arts Show will be ending, as will The Organist Entertains – which has been on the network for almost 50 years.
