The commitment means apprentices will be employed at every BBC local radio station across England and in BBC radio stations across Scotland, Wales and Northern Ireland.
Apprenticeships provide an invaluable path to successful employment and long-term careers for youths who may lack a university degree.
The BBC says the posts announced by the Director-General today are in addition to existing schemes in Bristol, Salford, Birmingham, Cardiff and Glasgow and previously announced apprenticeships in Production Management, Radio 4 Journalism and a degree-level apprenticeship in Broadcast Engineering.
Announcing the new opportunities, Lord Hall said: “I believe passionately in apprenticeships.
“This announcement of an additional 45 BBC apprentices demonstrates our commitment to broadening the routes through which talented young people can join the BBC. It also reaffirms our commitment to investing in talent from the broadest possible range of backgrounds and communities across the UK.”
