Artists gear up for Mobo Awards

Singer Amy Winehouse and British rapper Dizzee Rascal lead the nominations for this year's Music of Black Origin (Mobo) Awards, to be held later.

Winehouse, who recently performed at the Mercury Music Prize show for the first time in several weeks, is up for four awards which include best female.

The 24-year-old has confirmed she will perform at the ceremony, which is being held at London's O2 arena.
