Steps are number one in the UK album charts with 'The Ultimate Collection'.

This collection was released on October 10, the same week that they announced that they will be doing an arena tour in 2012, ten years after they split.

Last week's number one, James Morrison's 'The Awakening', is now at number five and the self-titled album from Evanescence is at number four. 

Ed Sheeran's '+' is at number two and Adele's '21' is at number three, for its 39th week in the charts.
