Weekly entertainment and chat show programmes will also be part of the line-up for "STV2," which will broadcast for 24 hours a day, seven days a week.

STV will be staging outside broadcasts across Scotland as part of its its weekday magazine Live at Five, which was peviously shown on STV's Glasgow and Edinburgh channels. They are being merged with new licences for Aberdeen, Ayr and Dundee to create the new station.

Bobby Hain, director of channels at STV, said: “STV2 is the new channel for Scotland designed to reflect life across the country.
"The channel will provide a unique opportunity to broadcast content that isn’t available for viewers anywhere else, including in-depth coverage of local sport and live events and exciting acquisitions including soap and drama, alongside an enhanced news service with local, UK and international stories."
