Plans are in place to launch a a 24-hour news radio service on the soon to be awarded second commercial national digital multiplex.

The details have been announced by BSkyB and Chrysalis Radio who form a joint venture to launch the service, to be known as Sky News Radio.

The two companies make up the consortium bid for the licence headed by Channel 4.

Sky News Radio is intended to be launched next year if the bid is successful.

The 24-hour rolling news service will bring news and analysis from the UK and around the world.

Chrysalis Radio's existing London rolling news station, LBC News 1152 AM, will also be incorporated into the joint venture, and will be rebranded as 'Sky News Radio for London'. The station will become a regional "sister station" to the national Sky News Radio service, with relevant local news, traffic/travel, weather and sport for London retained as part of its output.

Sky News Radio will also be made available via the internet and Sky's digital satellite platform in due course.

John Ryley, Head of Sky News, added: "We're delighted to be working with Chrysalis to expand our involvement in UK radio. This partnership will build on Sky News' strength in rolling news, extend the reach of the Sky News brand and increase choice in news radio in the UK."
