Global is to end all local and regional shows on Heart, Smooth and Capital brands in England, adopting a new Nations Strategy.
Output will continue on a national level in Scotland and Wales.
The move has been made possible following the introduction of the Media Act late last year, meaning the current regional breakfast shows on Smooth, plus drive shows on Capital and Heart, will end.
All of the output for Capital, Heart and Smooth stations in England, including those owned by Communicorp, will be broadcast from London.
