London (BFT): Chart-toppers One Direction led the UK’s global sales charge last year which ensured home-grown acts accounted for one in every eight artist albums sold around the world, according to new figures. The group’s third album Midnight Memories was the biggest-selling release internationally, giving British acts the top seller for the sixth year out of seven. It clocked up sales of four million in the space of six weeks, beating US rapper Eminem into second place.
